Any tips on introducing a new lil kitten to our home of older kittens and cat? We have 3 older kittens, all above 17 weeks old. and tonight we are being given a new kitten who was abandoned at the vet and we are adding her to our home. Any advice? I know my cats will accept her, but this poor thing has been through some traumatic experiences and I'm not sure if she will accept the other cats. I'm just worried about her. Just a note they have all been fixed including this new one and all up to date on shots and tested for everything.
