Hello, We have a 13 week old male tabby, Alfie. About ten days ago, we brought my sister's cat, Martha, who is a female indoor cat and around 2.5 years old, to live with us. Martha has always been very timid, and isn't very sociable. Alfie, on the other hand, is extremely sociable and outgoing. We kept Martha in one bedroom for around a week, with a few short introductions to Alfie, which generally involved Alfie trying to play with Martha, and Martha hissing and growling. Martha is comfortable in her new bedroom now, and is keen to explore the rest of the house, and also seems keen to meet Alfie when she sees him through the glass door. However, this weekend we have tried to let them spend more time together, with the following results... As soon as Alfie sees Martha, he chases her, generally into Martha's bedroom and under the bed. Martha is still growling and hissing, and lashes out but not in a particularly vicious way. I have read that the existing cat will chase the new cat away from 'their territory', but I'm not sure that Alfie is doing this. Rather, I think he just wants to play with Martha. Alfie doesn't hiss or growl, and when Martha is closed away in her bedroom Alfie meows and looks around for her. Also, Martha does seem to want to say hello to Alfie, but just gets put off when Alfie sets off after her! So I'm not sure that Alfie is particularly 'bullying' Martha (he is about a third of her size!), he is more just over excited about the prospect of a friend. But Martha is not so enthusiastic about constantly being chased and pounced upon, and it seems that the growling and hissing will never end. So is there any advice about how to introduce an older more timid cat to an excitable kitten? And does it sound as if this friendship might work out, or is a lost cause? I would love for it to work out, because Martha has been moved from place to place her entire life, and it would be nice for her to settle for a while. Thanks in advance!
