I buried my newborn kitten, is the poor thing definitly not alive?

The kitten was definitely not alive. it was cold, not responsive, and during the time you were waiting to see if there were signs of life, you probably watched very carefully for any breathing etc. You tried your best but it was already gone. So you did the right thing to bury it.

Now just keep the mother cat and kittens in a warm, dimly lit room, keep the door closed to keep the mother in with the babies and prevent her from moving them to other places where you might not find them or might not be able to reach/ see to check on them. ( A nervous mother cat sometimes will keep moving the kittens to new hiding places Keeping the mother and kittens in a separate nursery room is also to keep it peaceful in there without other pets, kids etc. running in and out which may stress her out. The more happy and peaceful you can make it for Mama Cat , the better she can focus on caring for the kittens. Young mother cats sometimes are still immature and may need some encouragement to be a good mom. So if she wants your company, do try to spend time with her in there and give her some attention.

She needs to be eating canned kitten food for the protein, calories and moisture. Nursing takes a lot of energy and hydration.

You can get her spayed whtn the kittens are 8 wks old. but if you can keep them a few weeks after that it gives them a better start in life. Kittens are much more ready to be independent by 10 or 12 weeks. .

No, you are perfectly correct by the sounds of it. You tried your best and waited for a response but unfortunatley its nature.

Good luck with the rest of your kitty's :-)

if you checked before and there was no sign of life, it is definitely not alive. god bless the poor thing :( xx

Well, if he/her wasn't dead before he/her will be now if you've buried the him/her

if its dead it should get rock hard within an hour
