Right, I went into the kitchen and there on the windowsill (on the outside of the window

) was a
beautiful tortie-and-white. I was confused for a minute, thinking "Hey... That one's not mine..." (

) as she shifted around a little bit, while looking at me. She kept looking down and then scooting, and ended up on the lefthand side of the sill. Boom, Ninja jumped up beside her! So they sat there and stared at me for a while, and I held up the pouch of catfood (

) to show Ninja it was foodiestime, and emptied it into his bowl, and put the bowl into the carrier.
In he came, with me standing just off to the side where he couldn't see me but I could see what was going on through the pebbled glass of the door. Into the carrier, one leg still sticking out. I stepped to the side and stood in the door opening, thinking "Can I make it if I jump out, push his leg in and then shut the door?" but ultimately didn't think I could and thought it would give him the fright of his life if I tried.
He came back out with a mouthful of food, dropped a bit, spent a few minutes looking annoyed until he found it again (

) and then noticed the tortie was by his hole and went to nose at her, eventually going back out. Having left the vast majority of his breakfast.
I'm giving serious consideration to buying a humane trap

and wondering whether it's really worth the trauma and pain for him, given even a vaccinated cat can still infect unvaccinated cats. Might it not be better if we get the kittens, keep them apart from him until they're fully vaccinated if they haven't been, yet, and see about getting Ninja to the vet's when he's had a chance to learn from them that neither we, nor the carrier are
quite as dangerous as toxic waste?
