We have had gerbils for a while now and things have always been good. Back in December, we went out and adopted 2 male gerbils from the local pet store. they were the same age and I was told, from the same litter. Though, I am not sure about that since they were very different types. Anyway, they had been living together in the same cage at the pet store along with other gerbils. Last night, i found one of them dead in the tank. it was shocking especially since neither of them had shown to be sick and they are both young! i would say about 4 months old. The most shocking part was the condition of the dead gerbil-it was quite gory and revolting to say the least. Now, i am not sure if the surviving gerbil "murdered' the dead one or, if the dead one had been in the tank for a while before I noticed and the surviving one went a bit cannibalistic on it. Either way, I am creeped out. any ideas people?
