My cats started out friends. 1.5yr old and a kitten. Sleeping on each other, grooming each other etc.

Then the kitten hit puberty and they were bitter enemies until the older one passed at 17. The younger is now 16 and living his best life. I’m glad yours got on eventually. We tried everything with ours, but the best we got was when they would deliberately ignore each other for a few years

I haven’t had a printer since early 2020 when I was last in the office. Sometimes I definitely miss it. But not enough to buy one.

Since then, the only thing I’ve needed to print was a visa which said I must carry a printed copy, but at the border it was digitally attached to my passport, so turns out I didn’t need it at all.
