Now that we're down to one cat again, I thought it might be good to
adopt another cat or kitten.

I find myself going more toward a young cat as opposed to a kitten
because I know most people adopt kittens first.

I'm trying to convince the SO that going with a cat between 1-4 years
old isn't such a bad thing. First of all, they've had all their shots,
have been spayed/neutered and their personalities are pretty much fixed
at that point.

Not to mention the fact that you're probably sparing the cat an early
death.

Of course if we adopt another cat it'll be the traditional way. Surfing
petfinder.com is one thing, but going and meeting the cats is the best
way. Friendly cats are the ones trying to jump out of the cage. That's
how Cosimo came into our lives.
