I forgot to update this when we got a new cat. Back in May 2020 we took in a mama cat and her 5 kittens. They were on a construction yard and the crew there didn't want them getting killed by heavy equipment so they had caught them all and were looking for a foster home.
We took them but the mother was totally wild and wouldn't let us near her. She also rejected her kittens once they were all moved to our garage. We tried to get her an appointment to be spayed but with Covid there was nothing for a couple months, and she escaped while we were waiting.
So the kittens were only about 3-4 weeks old. We got some kitten bottles and hand fed them formula for a few weeks, introducing solid foods slowly.
All 5 did great. We kept 1 of them, Smokey, and found homes with friends for the rest of them.
Our dog Kira liked the kittens right away, but our 10yr old cat Mischa was less enthusiastic. Her and smokey mostly get along now but still have the odd brawl now and then.
Smokey is probably the most affectionate cat I've ever had. He'll often come into our bedroom during the night and jump up on me and start bonking my head, purring like crazy. He wont' go away until you give him enough petting. He lets our 3yr old also carry him around and he'll sit with the older kids for hours, jammed half way under a blanket. He's also the most efficient killer we've ever had, so many dead mice, and robins (which I'm ok with since they try to eat my grapes, even with them all netted).
