I took my bun in to be neutered this morning and at the mo am concerned. He has pooed luckily and had a bit of syringe food and grass the vet at about 3pm, and came home about half 5. It is now half 11 and with the exception of about 2 small mouthfuls of carrot... I have tried tempting him out with carrot, kale, sprouts, broccoli, his normal excel pelets and hay and he just won't eat. I am going to take him straight down to the vets in the morning if he hasn't eaten, but have just prepared a gooey mess... Boiled some water and melted aload of his excel in it, but am not sure how much to syringe feed him when it cools down as I don't want to waterlog him and also how to do it, as have only used syringes externally on my pets before. Any advice would be really appreciated. Thanks in advance
