Rebecca, I hope all goes smoothly tomorrow with the 3 cats heading to the vet. You'll certainly have your hands full! You're doing a wonderful thing and it's so great that by tomorrow afternoon, your 4 house cats (including the already neutered male you have) will all be fixed! YAY!!! I know you have the ferals booked for May which is awesome too!! We'll be thinking of you tomorrow and look forward to hearing an update on how your lovebugs are doing. Take care.
p.s. is there a quiet room in your busy household that the cats can use to 'recover' in for a few days once they're back home? I know your daughter's room is already booked with a four legged guest and her mini meowers.
