Need advice about adding a 3rd cat
My fiancé and I have two 1.5 yr old male Burmese cats that I brought into the relationship. When she moved in with me about 6 months ago, she had a cat but decided to leave it with her old roommates, as the cat was happy and comfortable there with the cat her roommates have, even though I would have welcomed the cat with open arms, as she (the cat) was family.
Anyway, a good friend of my fiancé very recently got a 5 week old female kitten even though she has a 16 month old daughter. For various reasons that are not surprising, she now wants to find a new home for the kitten. My fiancé wants to take this kitten in, partly because she wants to give the kitten a good home, partly because she wants a cat of her "own" even though current cats are effectively "ours" and they love her and she loves them very much.
The idea of adding another cat makes me very nervous. We are in an 1100 sq ft apartment, and I feel our cat situation is perfect. They are very happy and content. I do not feel the need or desire to add another cat, and am only seeing the downsides: the risk of incompatibility with the current cats, the added responsibilities, space issues, behavior issues, etc. However it is very important to my fiancé to take this kitten in, and she insists that 3 cats is no more worry than 2.
I feel that bringing another animal into our lives is a major change, responsibility, and commitment that should only be done if we are both comfortable with it. Is that unreasonable? Am I being overdramatic with my concerns about the possible downsides of adding a kitten into the mix? Is is really not that big of a deal, and not much different from having 2 cats?
