I just took Mabel in to be spayed yesterday and she is 25 weeks but is only 3lbs 5oz. I worried more about her smaller size then her age - as someone mentioned yesterday, they had their hamster spayed so maybe weight shouldn't be an issue either. I know that vets will spay kittens and puppies sometimes when they are only 8 weeks old. Hopefully someone who is more knowledgeable about this will answer your question. Good luck! |
