We've gone away and mum is house sitting our 2 Burmese. They know her well. One hasn't been eating much and needs encouraging with hand feeding. Otherwise full of beans but is scent marking with his face all the things that are ours. The other cat is fine. I'll get her to take him to vet for check over if doesn't improve. He's the high maintenance/sensitive one of the pair and follows me everywhere. They get on great. I didn't think cats pined for owners though. Any thoughts?
