Oh no! That is so sad! Were they sick? She lost all of the kittens in her last litter as well right? And her sister did too? Are you able to get both of the moms spayed now?
There is nothing to hate. You are doing an amazing kindness for your girls. Don't worry.I know and that's sad. I really wanted a kitten from her. Yea she was a good mommy. She took good care of her babies. Her sister hasn't gotten pregnant since her first liter. As soon as I can though, we plan on getting them fixed. I hate it but it has to be done.
