Thanks for the insight . I can guess all the animals which Allah made for benefit of humans , *which are pleasing to look at or which are good to be pet will be in Jannat but all the bad ones will be in Jahannum to intensify the azaab of jahanum. But then on second thought what did those bad animals do wrong to be in Jahanum. *
I don't think so, they will simply not exist in jahanam. Although in Quran & HAdees there are refrences about giant snakes and other animals, but I think those refrences are given in order to give us a close description of their physical attributes. There will be an entirely different breed of animals there. Wallau allam.
