I have a pair of rabbits since last 4 months..female rabbit giving birth every month..after 1st pregnancy and births she was normal but after giving birth second time she started loosing weight..the male rabbit is also losing weight ..although they are eating normally..there is no change in their dietary habit...I give them grass after every. 4 hours and they finish it within minutes...female rabbit is feeding her babies so it can be a reason for her weakness but what's wrong with the male..I'm taking good care of them but still their weight lose is really making me worried..plz help me with this issue as I don't have any access to some vet
