Rats can be wonderful pets that are easy for young people and adults to take care of. However, as a rat ages, it may lose the use of some of their limbs, which can make caring for it a little more complicated. The most common causes for rat paralysis are stroke, tumors, and bone deterioration due to old age. If your rat has lost the use of its hind legs, it's essential to care for them properly or else they will suffer from pain. Proper care includes identifying problems quickly so they can be treated effectively and making changes in your rat's housing and daily care so that the animal doesn’t develop sores or skin infections.[1]
