Tinker is gorgeous! hope he gets well soon.
Our cat Friday gets quite severe plaque build up & has to go quite regularly to have her teeth done (the vet says "she's got quite a mushroom there" ?!)
she lives with my parents, so I couldnt tell you how much it costs each time. She now has an inoperable tumour on her tongue, so is on £25 a week (or fortnight?) Metacam, and the most expensive food in the supermarket
do you notice that your vets seem to charge so much more for "pets" than livestock?
