It all depends. When I took one of my piggies it cost £25 but that was for the first consultation. It also depends on the antibiotics given. Baytril doesn't usually cost that much. Around £4 I think. When my vet first prescribed me Septrin, they had to order it in. It cost me £10 at first but it was then cheaper after that. It all depends on the vet practice and what your pet is there for. Connie has a lot of problems with her bladder but after the first consultation, the fee came down each time and sometimes I wasn't charged at all xx
