Domesticated rats (Rattus norvegicus domestica) are beloved pets for their friendliness, charisma, and intelligence. Unfortunately, they’re relatively short-lived and prone to benign and malignant tumors. Curious pet parents or those considering rat pets often wonder when to euthanize rat with tumor.
Euthanasia is the best option in rats when the rodent has multiple tumors. A humane death is also necessary if the tumor size is at least 3.0 cm (1.18 inches) in any direction. Other health status implying a need for euthanasia includes untreatable pain or if a rat has lost at least 20% of its usual body weight.
In this article, I’ll discuss when to euthanize rat with tumors. I’ll also discuss when to euthanize and when euthanasia is unnecessary.
Is It Humane and Legal to Euthanize a Rat With Tumor? What to Do
Euthanizing a rat with a tumor is humane and legal, especially if it’s experiencing immense pain and distress. Malignant (cancerous) tumors are often inoperable and can quickly impact a rat’s life. However, some benign tumors can be removed, making euthanasia unnecessary.
There are two crucial standards your pet must meet for you to euthanize it lawfully. They include the following.
- Your rat must be medically ill or injured that death is inevitable
- Your pet must be medically unfit to live any longer
Whether it’s humane or legal to euthanize a rat highly depends on its tumor type. It’s imperative to seek a proper diagnosis from a qualified vet before giving your furball a humane death.
Some tumors are more evident than others, although they all present signs like pain, discomfort, and mobility issues. A vet can help you determine a tumor’s size, location, and invasiveness through physical exams, ultrasounds, and X-rays.
Furthermore, a vet can do a biopsy to help determine whether a tumor is malignant or benign.
Benign tumors are often operable, mainly if not located in the brain. They can be removed to alleviate discomfort, increase mobility, and ensure your rat has a fair chance of living a full life.
The ideal course of action highly depends on a rat’s diagnosis. Some types of cancer don’t need surgical removal and can be treated effectively with medications like Tamoxifen.
On the other hand, some cancers are highly invasive and quickly compromise a rat’s quality of life, making euthanasia necessary.
What to Do
Under animal cruelty laws, it is illegal to “kill” a pet in a shocking, torturous, or inhumane manner. The offense carries penalties, including jail time, probation, or fines. Therefore, it’s morally and legally safer to depend on a qualified vet to help euthanize a dying pet rat.
If you must euthanize a rat with a tumor in person, the most humane way is to expose it to highly concentrated carbon dioxide.
How to Euthanize a Rat With Tumors
If your vet confirms your pet rat won’t survive the tumors, euthanasia is the next course of action. In such a case, here is the procedure to euthanize a rat with tumors:
Step 1—Gather the Necessary Supplies
You’ll need the following supplies to euthanize a rat with a tumor using carbon dioxide:
- 1-gallon vinegar
- 1-pound baking soda
- Shoe box or tin
- Huge plastic container and plastic bag
- Tape, twist ties or rubber bands
- Cage litter, cloth, or shredded paper
- Plastic zip lock bag
Step 2—Assemble the Euthanasia Chamber
The first step is to make the shoe box as cozy as possible for your rat by adding shredded paper, cage litter, or a cloth.
Only leave a tiny nesting area for your pet to ensure it doesn’t move excessively during the euthanasia procedure.

Step 3— Add Baking Soda to the Plastic Container
The next step is to put the plastic container into the huge plastic bag before pouring baking soda inside. Place the nest (shoe box) with your rat at the center of the plastic container.
Step 4—Begin the Euthanasia Procedure
Hold the ends of the plastic bag and leave only a tiny hole to pour the vinegar into the plastic container with baking soda. Start by pouring a liter or two of vinegar and tightly grasp the ends of the plastic bag to limit air passage.
The baking soda and vinegar solution will generate carbon dioxide, inflating the plastic bag. Give it a minute or two before pouring the remaining vinegar. Close the ends of the plastic bag using tape, twist ties, or rubber bands.
Your setup should resemble the one shown on the image.
Step 5—Confirm Death
Euthanizing a rat with carbon dioxide is humane because the procedure kills in just a few minutes. Still, it’s safer to leave the euthanasia chamber intact for an hour before confirming the death of your pet. Once you do, place your furry friend in the small plastic zip-lock bag and dispose of its body.
How to Decide When to Euthanize Rat with Tumor: 3 Important Factors to Consider
Deciding to euthanize a pet rat with tumors can be challenging and emotional. You must carefully consider your pet’s welfare, quality of life, and chances of recovery if treatment is an option.
Here are some guidelines to help you determine whether it’s best to put the suffering to an end:
1. Type of Tumor and Prognosis
Rats are genetically predisposed to a higher risk of developing malignant or benign tumors that can impact their quality of life or cut short their lives.
While malignant tumors are cancerous and life-threatening, benign or fatty tumors are less harmful.
Some common types of tumors that can develop internally or on the rat’s skin include the following:
- Keratoacanthoma: Benign tumor that develops in the skin around the tail, back, or chest.
- Mammary Fibroadenomas: A benign reproductive tumor that grows on the mammary tissue.
- Mammary Adenocarcinomas: A malignant tumor that grows anywhere from the chin to the tail.
- Testicular Tumors: Is common in male rates and grows in the testes.
- Pituitary Gland Tumors: Common in female rats and cause depression, head tilting, and sudden death.
Whether you should consider euthanizing your rat depends on the prognosis.
If a tumor can’t be surgically removed, is bigger than 3.0 cm (1.18 inches), or has a poor prognosis, euthanasia can save your pet from enduring horrific pain and suffering.
2. Available Treatment Options
Often, your rat can benefit from treatment options if a tumor is caught early.
Some tumors are easy to diagnose because they can be felt or seen externally. Unfortunately, you may know of a concern too late if a lump is in the internal organs and can only be diagnosed using X-rays or scans.
Moreover, the availability of treatment options may depend on the type or location of a tumor. Unfortunately, some tumors can’t be surgically removed without posing the risk of worse complications.
Additionally, some tumors grow too rapidly. They give treatment little or no chance of delivering a positive outcome. In such cases, you may consider euthanasia to prevent further suffering.
3. Pain and Suffering
You can tell that pain and suffering are at their max if your pet has multiple tumors or has lost over 20% of its usual body weight. Merely because a tumor is operable doesn’t necessarily mean it’s better to seek treatment.
Some rat tumors cause devastating symptoms, including but not limited to the following:
- Immense pain and discomfort
- Changes in feeding and sleeping patterns
- Difficulty walking or climbing
- Deformed head and bulging eyes
- Neurological impairment
- Paralysis and seizures
You may want to consider euthanasia if your pet has little chance of responding well to treatment because its health is already severely impacted. This is also the humane option if your rat’s condition has no improvement and its health worsens even after treatment.
When Not to Euthanize Rat With Tumor
Rats are prone to various lumps and growths, although not all are cancerous. Some tumors, such as lipomas or benign cysts, can be surgically removed to prevent them from affecting a rat’s quality of life.
You should only euthanize a rat with a tumor if:
- The tumor is untreatable
- The prognosis is very poor
- Euthanasia can help prevent prolonged pain or distress
Cancerous tumors are not always a death sentence, especially when caught early. Many don’t regrow if surgically removed before they reach 3.0 cm (1.18 inches) in any direction.
Always consult a qualified veterinarian to assess the rat’s health and discuss treatment options. Seeking early treatment will give your beloved furry friend the maximum chance of living a full life after recovery.
If you can’t dodge the possibility of euthanasia, your vet can also ensure the procedure is done humanely to save your pet from unwarranted distress.
Can a Rat Live With a Tumor?
A rat can live with a tumor depending on the type of tumor, its size, and its location. Moreover, the rat’s age and overall health can help evaluate its chances of survival. For a more definitive answer, it’s imperative first to have your rat diagnosed by a vet.
The most critical factor that can help establish whether a rat can live with a tumor is the type of tumor it has. Benign tumors are slow-growing, non-cancerous growths that some rats can live with comfortably. These growths can also be removed to prevent them from putting pressure on surrounding organs and make movement easier.
On the other hand, malignant tumors are highly aggressive cancerous growths. They pose a bigger threat to the pet’s health and significantly impact the chances of survival. Tumors located in critical regions like the brain also cause more severe problems, shortening a rat’s life expectancy.
Furthermore, the odds of a rat coping with a tumor highly depend on its age and current state of health. Older rats or those with a compromised immune system have little or no chance of living with a tumor.
How Do You Slow Down Tumor Growth in Rats?
The most effective way to slow down tumor growth in rats is through dietary support. Although there are no guarantees, most rats respond well and show a decrease in tumor size if fed nutritious, low-fat diets. Some foods linked with a reduction in tumors include miso and curcumin.
Although not all dietary treatments are scientifically proven, some effectively prevent tumors or slow their growth.
For instance, you can lower the risk of tumor development by ensuring your rat maintains a healthy weight and its protein intake doesn’t exceed 12 to 14%.
Moreover, foods containing Quercetin, such as dark greens, cherries, and berries, can help prevent tumors by absorbing free radicals and protecting cells from damage.
Here are other tips to help slow tumor growth in rats:
- Feed soybean products like miso
- Include anti-lump mixes in your pet’s meals
- Only provide diets low in proteins and fats
- Provide high-calorie meals if your pet is losing weight fast
- Include curcumin or turmeric supplements in your rat’s diet
Final Thoughts
Although not all tumors are a death sentence, some cause significant discomfort and suffering. They make it necessary to make the compassionate and humane decision to euthanize your furry friend and save it from unnecessary pain.
If you suspect your pet rat has a tumor, it is essential first to seek veterinary care.
A veterinarian can diagnose the type of tumor and guide you on the best course of action, whether it’s surgical removal or palliative care to help manage the rat’s pain and discomfort. Most importantly, the expert can provide reliable guidance on when to euthanize rat with tumor.
