Cat shelter

Why did you do it in the first place?

They had to much hair everywhere plus cat litter baby crawling everywhere im about to give birth to another financially hard at the moment plus they got fleas again, just want them back and the place said im not allowed to adopt them back

As horrible as it sounds, it's probably best not to get them back. Rehoming isn't just a quick decision and if it was, then they deserve to be in a home with someone who won't give them up. The rescue is doing the right thing by not letting you have them back. I'm not saying you're a bad owner but rehoming can cause so much stress for animals, so if you've already given them up once, there's no saying you won't do it again later, especially once your baby arrives. Work through the loss, work on getting to a better place financially, focus on your children.
