Bass seems to suddenly have a lot of loose skin on her. She's always had a bit but I'm sure it's got worse lately. She's eating normally and doesn't seem to have lost any weight - could it be her age (she's 12)? I also wondered if it might be dehydration - although she eats mainly wet food, she doesn't drink very often. I dont want to cart her off to the vet unnecessarily but I'm concerned it might be a symptom of something.
