August 6th. It was a mostly digested mouse, and it was just after he'd had a massive poop. He went right back on food 2 weeks later, and had been mostly regular afterwards. Every now and then he'd refuse food for a week, but never for really long. Like I said, he's a bit fussy.
I'd planned on giving him a bath with shed ease to get his stuck shed off, that would help with hydration, but should I specifically ask my vet for that too? She doesn't have space to see me til Monday.
Thanks guys, this helped my worry a little less over his not eating. Now it's just the concern about his mouth. ):
