What word can I use to refer to ALL cats: domesticated, house cats, tigers, lions..etc? ?

Feline refers to all cats domestic and wild.

First of all, it sounds like you're a nice caring soul and it's great that you're helping these stray cats. You can domesticate a stray although cats have very distinct personalities. I have two cats, one that was an adult when I adopted him who's extremely friendly and cuddly and one that was a kitten when I adopted him and he'd love nothing more then to stay outside! If you do decide to bring the cat in, you can get a fairly inexpensive plastic litter box, and there are various types of litter to put inside of it. You do have to clean it fairly often to make sure the cat will want to use it. Cats will often train themselves to use it because by nature, they like to urinate in the same, clean place and most household areas aren't comfortable for them. If the cat does have any fleas at all, I would recommend buying some advantage. It is really important though, that your parents will aprove of it. If they don't, it may be a good idea to call animal control again and if the cat is adoptable, they will help place it in a shelter to find a good home. Good luck!
