Hi everyone,
I've noticed over the last few weeks that our kitten has a small bald patch on her chin (which she didn't have before, as far as I can tell). She's seen the vet since then for fleas at the start of the month, but he didn't notice anything and we weren't worried at the time; we didn't mention it either as it was barely visible.
Except for about a week now, I've been wondering if it's spreading a bit towards the corners of her mouth. She doesn't seem to be in pain, and I don't think it's swollen. She’s eating, drinking, using her litter tray and playing as usual. I feel like she’s dribbling a bit when she’s happy during a cuddle session: she dribbles on me whereas she didn’t before, I think (just a few drops).

We changed her diet a little under a month ago. I can't quite tell if the timing matches up, but I'm pretty sure she didn't have this problem before.
We’re giving her Feringa wet food and Purizon (she’s still on a 50/50 transition with Royal Canin because we had a full bag left over). Do you think it could be a reaction to the dry food or the wet food?
We’re going to the vet on Monday for a vaccination, but I’d love to get some opinions before then, thanks! :)
