Why do you? Same reason, old age.
No. All pet rats are vaccinated.
heart failure is not common in rats, as they usually die from tumors.
Well it mostly depends on the health of your rat. I myself have rats. Male rats are more likely to get tumors than females though. Hope this helps!
You can find pet rats in a lot of pet stores, or animal rescues. You can find wild rats just about anywhere.

The life expectancy of rats with mammary tumors can vary depending on the size and aggressiveness of the tumor, as well as the overall health of the rat. In general, untreated mammary tumors in rats can lead to a decreased life expectancy, with some rats surviving only a few months after diagnosis. However, with proper treatment such as surgery or medication, some rats may live longer. It is important to consult with a veterinarian for the best course of action for your rat.
Pet rats are not vermin. Pet rats are raised in a pet store, laboratory, or adoption center and they are raised to be pets or in the case of labs, experiments. if you are thinking of buying a rat remember not to buy a rat raised as food for snakes. Rats bred to be pets are much gentler and sweeter than rats raised as food.
they are slow moving and will die very soon, their not very active Depending on what type of tumor you are talking about. Female rats are susceptible to mammary gland tumors, which usually aren't cancerous. But they do grow, so as soon as you see one (feel you rats all over regularly) have it removed. One of my rats has had about 9 mammary gland tumors so it is best you buy your rats from a reputable breeder, not from a pet store that gets their rats from "rat mills," which she was. Rats can also get cancerous tumors. Watch for suspicious bumps and lumps and if you find any, take them to the vet ASAP. If you can't afford to take your rat to a vet, then you really shouldn't have any. They can be costly and people often think of them as disposable pets, but they aren't. They are just as smart as dogs and you can teach them many things. They don't live long (2 - 3 years) and they depend on their owner to keep them safe and happy.
