Thank you, Becky! I got a call this afternoon that Dr.Bleifer is very ill and unable to do the neuter but Dr.Casey will do it. She's a good vet too. I'm anxious for them...about the part of not feeding them after midnight...i have to remember to not give them any water either tomorrow a.m. , and about their recovery period. Tonight i gave them a little xtra food and fried bacon(!), and will give them a little snack soon too. They're probably wondering why mom's being so generous all of a sudden! I'll keep you posted on how it all goes!
