Help! New mother cat just had leg amputated! Kittens and mother all going crazy!?

The kittens are crying because they smell Mamma but are having trouble nursing from her. They need time to adjust. Mom doesn't like being in the cage with her kittens because you can see them in there. I would let her take them under the bed. She will probably settle down and let them try to nurse, which is the only thing that will help her start producing milk again. Mother cats have the instinct to hide their kittens and many will not nurse unless they feel well hidden, at least for awhile. Since she has been through so much and been away from her kittens for so long she should be allowed to take them into hiding. I would put the male cat in the cage if that is the only way to keep him away from her. She needs to feel safe from him. Male cats have been know to kill kittens because when the kittens are no longer nursing the mother will go into heat and that's exactly what he wants, even though he can't really do anything. Eventually, when she has settled in with her kittens, she may start to produce milk again. It may take awhile for her milk to start flowing again so you may need to sneak them away from her one at a time and feed them. You may be able to discontinue feeding them within a few days. You will need to watch for her to leave the kittens and then check them to see if their bellies feel full. She may already have gone into heat but allowing the kittens to nurse might pull her out of it. In a few weeks when the kittens are starting to be weaned she will go into heat again. Dad will try to mount her, grab her by the scruff of her neck and then stop and get a blank look in his eyes as if he forgot what it was he was going to do. It's kind of funny because that's exactly what he is thinking. Eventually he will stop trying. If the kittens don't seem to be getting any nourishment from Mom you will have to continue to feed them but they will start eating solid food sooner than normal. When they are three weeks old you can start offering them kitten food moistened with warm water. You can even mix in some canned cat food. If they are eating a lot of it you will want to mix their kitten formula in with it instead of warm water so they get all the nourishment they need. Hopefully you have been feeding them kitten formula like KMR because cow's milk will kill them. Human baby formula is even worse. Both have way too much iron in them for kittens and they will die of iron poisoning. I have raised many cats and orphaned animals as a volunteer for my vet. I have also raised many cats of my own. I am trained as a veterinary istant and animal rescue professional. Good luck!
