My two 8 month old, not-quite-kittens anymore have been tag teaming each other going into heat. We have had almost non stop yowling now. We need to wait 2 more weeks for their appointment. It’s a good thing I have earplugs, or would not sleep too well.

Other news, we made them a climbing wall with lots of activities, and they love it. We decided to keep them indoors. I have never done this before, felt pretty bad about it, but they don’t seem to mind too much, and we are determined to keep them from getting too boired.

Have you considered GrapheneOS? Not an open source phone as you say, but it is at least open source software, running on hardware with published specs. It should be capable of everything you want.
