wow... when I brought my boy to be neutered it was sooo very easy, on him & on me. He went in at 8am, I went to work, at 12pm they called to tell me he was done and coming out of anesthia, at 5pm I went to pick him up after work and they said he ate, drank, peed and pooped and he is still a little out of it, but fine. I took him home and he was like a little wild man! I dont know if the meds made him active, but he would NOT sit or lay down! I was nervous bc my vet uses skin glue, not stitches, so I was afraid he would bust open, but he didnt! He was a bit sore but overall he did soooo very well! and it was not overnight, thank goodness!
Good Luck! Im sure snickers will do just fine
