Good luck for today - a/d should be a set price, as it is the price the manufacturers set, You can only buy in cans of 24 online, so best to get it from your vet. I have never used it after a dental though, I normally cook them chicken for the first night, and they are generally eating normal food again by the day after (or with some of my cats, teh same night). Snowy had a large amount of teeth out in one go, and was hte only cat to struggle straight after, but it was a different vet, and they did a different anaesthetic, so I suspect that was the prob. Ginger had 6 out in one go, refused the soft food I had bought and asked to go out - but you could still see the anaesthetic in his eyes!!
