Annie had me all to herself for over a year. I was warned that she might not like sharing me and that cats, perhaps especially female cats, don't like other cats or sharing their space. I didn't even want another cat, much less two. However, I was out a lot and she wanted to play more than I could keep up with. So I took the risk of bringing her siblings. I figured if she didn't take to them, they'd have each other and I could stay focused on her.
I had gone to the shelter to meet a different pair of kittens, but it was Boris and Arlo who captured my heart. Arlo reached beyond the cage to pet my nose and Boris gave me eye contact like a long lost soul. They also seemed super-well bonded, never leaving each others side and each exploring whatever the other one had discovered or tried.
Trouble was, someone had claimed them already!
