Okay so I have a cat and she had a litter of kittens, she had four but the runt died maybe 4 days after birth. The three kittens left are now 4 weeks old and were all doing fine, I noticed yesterday that one wouldn't latch to mom, I tried to get him to eat a couple times hut he didn't want it so I figures maybe he just ate, well throughout the day same thing, he wouldn't eat and id try and make him latch, no such luck. He's quite weak and can't seem to keep his head up, we took mama and all 3 kits to the vet, the vet said basically to force feed them cause they're all anemic from fleas. She also said the one had what she thinks is a heart murmer...which i feel like she shouldve done something about? She gave us eye drops (they're eyes are crusty) and some extra protein food.& We bough formula as well. The vet basically said she didn't know if the one would make it and that we basically have to play the waiting game while trying to save his life. Honestly, I'm scared none of them will make it and it's gonna break my heart. I really feel like they should've gotten looked at better and some antibiotics. I have so much hope that they will all live but I think we are gonna lose the one...is there anything anyone can recommend..anything at all would be well appreciated. I'm just so crushes right now and wish I could've done more...I love them so much..
