Harris (3 years old) has always been nervy (ex semi feral kitten) but recently hes got loads worst. Now if anyone, person or cat walks near him when hes eating he stops and runs and hides. same if theres any noises, people talking, tv on etc. tried separating him from the others when feeding them but hes still not eating much, have tried loads of different food to tempt him including tuna but its the same he eats a few mouthfuls gets scared and runs away. hes losing weight because of it, going to take him to the vet for a check up, but is there such a thing as anti anxiety drugs for cats?? Not sure what else to try
