I’d love to hear about your quirky habits.
One of mine is that when I’m out in nature I tend to collect cool looking rocks, sticks, cones etc. My window sills have become a geology exhibit (and I have zero clue about what I’m collecting, I just go by “ooh shiny”) and more often than not I’ll have small rocks in my pockets, bags, backpacks etc etc
Our previous cat had a persistent gi issue like that with constant runny stool. It cleared up after we gave her antibiotics for a UTI. For some reason the first round didn’t work, so the vet gave us a different kind which was brown and for dogs. After that she had normal stools.
