How do I get my current cat used to a new kitten?
(Ann Arbor, Michigan, USA)
I have a 7-month-old tabby cat I got from the Humane Society when he was 3 months old. He's been the only cat in the apartment ever since.
I just adopted a new, 3-month-old kitten last night from a family that had 10 other kittens, 3 older cats, and a dog. This new kitten is used to socialization but also used to defending itself and not being afraid to hiss.
I'm not sure what to do because they got along for the first hour or so, giving each other licks, but now they are at each others' throats.
My older kitten still seems kind of confused as to what's going on, but when he tried to play/wrestle with the kitten, the kitten will fight back hard and hiss.
I am having to keep them apart in separate rooms while I'm at work. The kitten was meowing really loud constantly when I left. They were even trying to get each others' paws under the door.
I need advice as to what to do. I've read all kinds of techniques online but I want advice from experts. Thanks!
