When will she have her kittens

I'm the same my cat got out through her heat season around January time shes so fat now , nipples are big and got either dried milk or dried skin around her nipples but goes off and on her food a lot I also can feel the kittens move it's too cute [emoji]10084[/emoji] but have no idea when she will have them

Olive and veggie oil are safe if/when ingested.  Baby oil is not.  You can also purchase Udder cream, yes for cows and also for lactating women.

Does the milk just leak out? or when you squeeze it does it come out? My cat's nipples look chapped and no milk is coming out yet.

Yes, when the milk begins to come in, tiny drops will leak out and dry on her nipples. They are probably chapped from being licked so much. You'll want to give her some relief by applying some oil as mentioned above. [emoji]128522[/emoji]
