That hardest part for the both of you will be the time apart. I agree, by the next day he probably should be back to normal, my Hannah and Puff got spayed, and since I worked at the vets, they let me bring them home when I got off work, instead of keeping them over, and it seemed to help them Tremendously!

Also when Stash had his surgery, at the feline vet I take him too, Because of his leg surguries, we had to get a special doctor for him, and his last surgery I got him neutured as well. I begged the doctor, and he finally gave me the go ahead to pick him up the same day!

I just feel like it is better to bring him home the same day, as at the vet, noone is there for observation overnight. Maybe you could ask the doctor to do the surgery as early as possible, and then see if he will let you pick him up before closing, because then you could observe him overnight instead of him being their alone all night. Might work, if you beg enough Just a thought
GOOD LUCK BRODIE!!!!
