When I was a kid, I loved dogs and my brother loved cats. When I was about 11, he got a little tabby-and-white kitten he named Fred (after an imaginary cat we had a whole pretend game based on), and I fell in love with him but still wanted a dog more.
We got a dog a year later, a lovely one-year-old bitch who'd been abused and neglected by her previous owners
and when I was about 17 we got another kitten when my French teacher asked if anyone wanted one.
I've been without cats since, but for a maximum of about 6 months. I don't feel right without a cat, and when recently I spent 2 months without I was reminded of just how weird it is to live in a house without a cat.
Of course, I only intended to get the one but am now ending up with a litter as well
I think if I had a dog who was about to have a litter of pups I'd have much more trouble with the idea, but then I don't want a dog - I've become a cat person. On one hand, I have a chronic pain problem and couldn't guarantee it the exercise it requires, on the other I prefer the feline personality.
I've also noticed if a dog jumps up against me I bruise really easily, and while I don't blame the dog for this (it is, after all, an animal) I don't want to deal with it on a regular basis. I will stop to talk to someone about their dog, we used to live nextdoor to a Staffie I absolutely adored - I just don't want a dog of my own.
