I’m new to Mario, but his flat doesn’t seem like an ideal home for a cat based on what I’ve seen so far.
I do think there’s an element of this with some vets, my local practice is terrible for trying to rip people off. I once took my dog in because she’d been stung on the nose by something & they started trying to flog me expensive dog food, £15 for three small tins! No offence to Mario but he does seem like someone who would fall for that sort of thing!He feeds the cat whiskers cat food I bet the vet saw him coming and has forced him to buy expensive and bespoke food. Now they both have IBS
