Hi Viv:
Hooray!!! So glad to hear little Snickers is doing so well and eating etc. You must be so pleased to have him home safe with you again, and to have the horrible surgery over with. Within a week you will find it hard to contain him. LOL. The constipation is usual and could be the drugs or the fact that the poor little thing was all cleaned out before surgery. I am sure someone here or the vet will be able to help if this continues. Sorry to hear he hates taking the drugs so much, but perhaps a little treat will make it easier for him.
Anyway, so happy for you and hope you both sleep well tonight and that Snick is soon fit and well and running around.
God Bless you little Snickers and keep up the good work.
Hugs and warmest wishes.
