I've come back after a weekend at my DM's with 29 small, round, red, very itchy bites. They're in two clusters - 14 behind my right knee and 15 on my lower back/bottom. My DM has two cats and her house isn't very clean. She immediately said 'My cats don't have fleas', and blamed my DF's dogs. It could be either, or neither, as I spent time in both houses, but was staying at my DM's. It could also be mosquitoes, I suppose, although I haven't seen any and it's rather early (and cold), for them, I would've thought? God, just writing this is making me itch
