I am currently having my first and only litter of kittens right now!!! The mother is only a year and a half old and seems to be doing fine, she is on towels in a closet and is taking good care of the two she already has but she has more in there and hasn't had a contraction in about an hour and a half, is there cause for concern? What should we be doing in order to help? Oh and we are staying away and letting her do this on her own, no noises, excess light or distractions, etc. thanks, Amber
