This product is OK for my generic "moggie" but has brought my Turkish Van Kedisi cross (with a ginger tom) out in a ruddy rash. She became very distressed and agitated and has been off her food for 24 hours. She now refuses to allow to me stroke her and is clearly afraid I will "hurt" her again. Beyer really do need a warning over this, as does my vet - which he will receive.
The maufacturer should clearly state in BLOCK CAPITALS that there is serious risk of adverse reaction to this drug. Vets should also explain that some cats can be seriously compromised by it.
