Pleased to report that all tests clear - his weight loss is due to stress!!

Vet prescribed Hills AD which he turns his nose up at, so now she has suggested kitten food, feliway diffusers and zylkene caps 75mg daily. Have read a number of threads both on here and moneysaving expert and am very interested in what the outcome will be. Not sure we can wait 4 weeks as if he doesn't start putting weight on soon, he'll be starved to death!!
