I live with two others - for context I have lived here for about 18 months more than them, as my previous flatmates got married and relocated and I have lived with my current flatmates for just over 2 years. I have an elderly cat that I rehomed about 3.5 years ago, who obviously predated my current flatmates so was here when they moved in.
My flatmate would like to get a puppy. I don't want to live with a dog, especially not a puppy. I don't have any concerns about being roped into looking after one or anything, and I am sure she would look after one very well, I just don't expect the cat would like it very much and I have no desire to have or be around a dog at home. But I know it is her home too and she feels strongly about it too.
I am in the happiest living situation I have been in for a long time after a couple of nightmare flatshares and I really don't want to fall out but I also don't want a dog. We genuinely all get along very well.
I'm not sure what to do - is it unreasonable to say no? Help!
