I caught my cat in the act on March 1 so this would mean she is 30 days along as of today... what should i be looking for? Her nipples are more prominant than before... when i used to look at them they were non exsistent but now they are there and a little plump. My question i guess is should i be feeling the babies yet and if i do feel them what do they feel like? I feel something like ribs along one of her nipples but maybe those are her ribs?
