Just called the vets to get the Kittens spayed and neutered as they will be 5 months old in a couple of weeks. The vet said they won't do it until they are 6 months old. I said that was crazy as I've seen kittens go into heat at 4 months old. She said yes that is true and would see if the vet would agree to do it at 5 months. She said it had something to do with the urethra not being fully developed until 6 months. I've never heard of that before. Guess I better start looking for someone else to do it
