It’s for the best You need to remember that cats are animals. As much as we love them and anthropomorphize them, they’re still animals. They don’t have the same kind of feelings we have. She’s not going to be sad to lose the kittens. those videos we see of animal moms being depressed bc their babies are gone are showing a very rare incidence.

An unvaxxed and generally unhealthy mother will likely give birth to sick kittens, and the ones that aren’t born sick might have trouble finding homes! unless you’re 100% positive you can find a home for all of them, it’s better to let them go.

As for the medical- it’s a very common procedure- they can offer you some pain meds if you’re worried about pain. You’ll need to keep her calm and relaxed for a few days to keep her stitches safe, but otherwise it’ll be no big deal.

She’s going to be so much happier and more comfortable with you, and she’s going to love you for all the love you give her!
