We adopted kitties from a no kill rescue group that pulls from high kill shelters (that are within a couple hour drive of us). Kitties in these shelters have about a zero percent chance - and I could look at kittens without thinking that they would be put down if I didn't take them. When we did adopt, we made space for more kittens who otherwise wouldn't have a chance.

It took me 6 months to be able to look at a kitten after we lost our Garfield. We lost him Memorial day weekend last year, and it was late October before I was looking. I was browsing one day and happened upon a Maine Coon look alike. He was going to be at a meet and greet, so we stopped by. I held him, I really liked him. Then, there was an adorable orange kitty - they put him in my lap, and I cried and cried. We thought about it. We talked about it. I was afraid I wasn't ready, but we kept thinking. My other half picked out a little white Siamese look alike that he wanted, and thanks to some foster parent confusion (the orange one might not be available), we ended up with the Maine Coon and the orange kitty. They were all in the 6 month range (the Siamese might have been younger) - and we could tell a lot about their personalities already (in fact, I thought the foster was wrong about a personality and I was right - the kitty just reacted differently to me). They're all special in their own ways. I'm glad we got them.

Just another thought and another perspective You're looking to adopt - whatever age you get, you're doing a great thing!
