Why is pain med optional when you spay or neuter your pet? I really dont understand this. We had our dog spayed just over two weeks ago and they asked if we would like the optional pain med ($30 package includes tattoo) we did take it and now we are sending our cat in tomorrow (wanted to do them both at once but cat went missing for weeks, because he got out) and again an optional charge for pain med (which again we are purchasing). Why dont they just add it to the price of the surgery and give an optional tattoo? Isnt it inhumaneto give your pet surgery and not give any pain med??
