I have a 9month old cat that has never been around another cat,she is very spoiled.We are getting a new baby kitten to bring home and I was wondering if cats in nature will be mean to the kitten.

Our 12yr old female cat urinates all over the house. Usualy in the same few spots.
She hardly ever uses the litter box, and this has been going on for quite some time now.
The cat is an inside/outside cat
It is not a super friendly cat.
What do I need to provide for the cat in the room to make it feel comfortable?
Will it ever urinate in the litter box?

SPARTA NOW HAS HIS OWN PROFILE!: www.Youtube.com LYRICS: I got this little kitty about 2 months back he was the nicest little kitty, now a pain in my crack This little kitty is a ninja, always stalking my feet This little kitty is a warrior you know what I mean he's an evil little kitty look what he did to my hand tries to get in trouble in any way that he can I could give this cat a toy, but he'd rather have the wrapper and I will always give him water, but he still drinks from the crapper You could lock him in a closet and he just won't care kitty chews on my shoes and he licks my hair always scratching on my favorite chair and jumping on the couch playing in the window sills and tearing through the house He's so full of energy and easily amused kitty will attack anything that moves Causing trouble, starting battles just so he could be a little part of he's a meanest little kitty so we named him sparta Hey little sparta what is with all the fight little bitty kitty wanna bite bite bite Hey little sparta what is with all the fight little bitty kitty wanna bite bite bite Hey little sparta what is with all the fight little bitty kitty wanna bite bite bite Hey little sparta what is with all the fight little bitty kitty wanna bite Where'd you go are you stalking me? are you under the couch, quite possibly ears laid back so you don't get caught ready to pounce my leg with everything that you got I know you're probably watching me from across the room concentrating ...

I have 2 female cats, neither spayed. The older cat ran out of the house for about 12 hours. She came home and now my other cat won't have anything to do with her. Including eat from the same bowl or be in the same room. Why is this? Will my house ever be back to normal?

About a month ago I adopted a four year old cat from a co-worker who was moving and could not take him with her. He has gotten along with other cats in the past. I have three other cats ages four, two and one. I have been introducing them to each other slowly providing treats when I do. I have also brushed each of them with same brush to get each used to each others scent. My problem is that they still seem to not get a long. I do not feel that I can leave my new cat have the run of the house yet with my other two. Any suggestions would be great. Thank you.
