I have great news
Sprout is OK, he has had his Ga and is coming round nicely. In fact he did so well under GA they even managed to castrate him
Now the not so good news. Once he was under and could see inside his mouth properly they found some nasty spurs on his lower molars that had grown into his tongue. This is why he couldn't swallow food properly or pick up any veg
His molars have all been burred back now but he has an extremely sore tongue, so it may take a while before he can eat any veg etc.
He had x-rays taken which showed very over grown lower molar roots. As he is so tiny the vet feels there is not much we can do to treat them, it will just be a case of pain relief and monitoring their progression. Thankfully at the moment there is no sign of abscess or bone infection.
We are still undecided whether to remove his incisors. They couldn't be taken out today as two of them are broken below gum level, The x-rays also shown they have incredibly long roots and Sprout has a very little mouth. It seems given the state of his molars he will need regular dentals so we can reassess the situation on a fairly regular basis. The vet's feeling was that if Sprout needs monthly/6 weekly dentals then its not worth attempting to remove them as they could be burred regularly under Ga when the molars are done. But if with a better diet his molars stay OK for many months then it might be better to attempt to remove the incisors to save Sprout having to go back regularly just for an incisor burr, especially as he is is so wiggly.
As Sprout is small and thin they were unable to get a blood sample even when he was under GA. But as his teeth are so bad and he did so well under GA the vet feels they wouldn't have told us anything as his condition appears to be solely down to his dental issues. If there is liver damage from being so underweight for so long , then hopefully it will right itself once Sprout can eat normally.
So a mixture of good and bad news really. But the the best news is, Sprout got through today and will be coming home to enjoy the rest of his life, however long that may be
