Thats right Helen it is. The veterinary one is relatively new obviously since the law of having to use veterinary licensed drugs first came about (or atleast became more strictly adhered to) its used quite often from what i can gather. Prior to this though neomercs was basically the treatment for most cats and i suppose there must have been the odd one who it didnt agree with most cats got on fine.
I may or may not be right in thinking that the veterinary type one perhaps doesnt need to be given so often ? neomercs were always twice or sometimes even 3 times a day depending on control, which for some folk with a very unstable hyper t cat found this abit difficult.
