Depends on several factors:
1. Do u have room for lots of cats? A 20-room mansion would not be strange with 8 cats. However, 1-bedroom apartment with 8 cats would be a zoo!
2. Can u afford to buy food, vet care, litter, etc for many cats? If you're a millionaire u can have just about any type or number of animals u want. However, if u r the lady using ur welfare check to buy cat food for 13 cats, we have a problem.
3. Does ur city allow u to keep many animals? Some cities do. Others don't. The lady who ignores city code to keep a menagerie of cats is probably a ''cat lady''.
4. Do u have a life? If u have friends, family, hobbies, etc besides the cats, OK. However, if u r the lady that lives alone, has no friends, no hobbies, never leaves the house, never talks to the neighbors.in other words, has NOTHING in life but ur cats.just holed up inside with ur army of cats, then I think u qualify.
As a general rule of thumb, I'd say more than 5 or 6 is getting a little weird.
