Can you get some KMR and small needleless syringes 1 -2 mls to feed them I know it's late. I will look for a temporary recipe you can make.
What do you mean what if the formula kills them? Why would the formula kill them?What if the formula kills them??
This is perfectly normal. My Cat also did this when she had kittens. They won't stay in the nest 24/7 in the wild a mother cat would have to leave the nest to go hunt to feed herself. in a home moma cat would be hungry and dirty not to mention need to use the litter box at some point and also just give her nipples a break from the suckling. The kittens will be fine as long as their nursing. I think my kittens nursed for about 5-10 mins every hour or so around the clock. More in the first few days as they had to work a bit harder to get anything.I cant live like this.... I mean the kittens suck on her teets for a long time and then she moves... Does that mean she has milk..... Would they even suck on her that long if she didnt have milk
