Who is his vet?
If I judge he needs to see the vet, will you pay for it?
Is there a limit?

Sorry for these questions but with Filou I never know these days. Here the rule is: the catsitter has to see the vet as soon as anything is not normal and we pay for everything the vet thinks useful (this is because we trust our vet fully).

Plus:
How often does he get food?
If in doubt should he gain weight or rather not? (my sitters always seem afraid they could starve and put way too much food in the bowls).
