Before it got so long, Alger came by and this time I managed to get out before he left again. I filled his bowl and he wolfed it down. After eating he rubbed his face on my shoes and purred at me. When I went indoors he left. I guess he doesn't want to hang around without me being nearby to run off the bigger cats. Still no sign of his litter-mates, though. I think they might be gone forever.
I hope the rest of the night isn't as long as the evening was.
