Alright this may sound weird but Kingsley is a 5 month old male spider who eats like a pig, lives the life cruisin in his cage, and chillin out. But, I went to pick him up the other day and his underside seemed soft and mushy, not strong a firm. Could something be wrong. He eats an adult mouse every 5 days (he's 150 g right now, I want him at 200, then I'll move down to one mouse every 7 days) I'm not sure if it's a sign of parasites or anything worse.... being a spider he comes from a reputable dealer so I would assume he doesn't have any parasites or worms. What could it be?
