my F-1 chausie had her first three kittens five days ago and Im not sure they are getting milk from her. on matter how I try I cant get any milk to come out of her or see any sign of milk on the kittens mouths. Im not sure how much a kitten weight it at birth but I did start to weight them and on 12-20 they were all about 7.0 oz one 6.8 one 7.0 one 7.1 and each day they gain 1 oz. so does this mean they are getting enough or should they gain more? all help would be great! thanks.
