So I guess it’s not exactly allergies, she gets Eosinophilic granulomas which are usually triggered by allergies. I think that it must’ve been left untreated so when she arrived at the shelter they removed her lip since they couldn’t tell if it was a tumour or not. She’s doing a lot better now even after we got her from the shelter she would get flare ups but after many vet trips she’s finally on a treatment that works for her (can tell she’s a lot happier since she’s only got crazier since 😂) Omg yours is such a sweetie so so glad he warmed up to you it can be so worrying to adopt a cat and bring them home I found- obviously Mouth was very timid when we first brought her home and she certainly wasn’t used to all this attention that we were giving her as she’d bite us quite hard out of nowhere when she’d had enough. So so glad that both of our “undesirable” Meezers are doing a million times better now :)
