I have a cat that CONSTANTLY purrs. You could kick him and hed still be purring. However, my question isnt about that cat, its about another. I have a 1 year old who doesnt purr at all. It usta worry me untill I realized that he does indeed purr. However he only purrs when hes sucking and kneading my house slipper which is usually at night. That is the ONLY time he purrs. Whats wrong with him? He a very happy and loving cat, why doesnt he purr? Why does his fossil of a brother constantly purr? He wants to be just like his hero, but if so, why not mimic the other cat's behavior and purr?
