well he is definat;y under the floor boards we have heard him running around under there, also he has eaten all the veggies I put out for him and been into his food, I went tp check the food this morning and the veggies were gone and he had been playing with his dishes! he is having the time of his life under there, too bad his brother is miserable, doodles has never been alone in his life. the thing that is making it hard to catch him is that he wont respond to thumping like all my previous gerbils did, in the wild they live in borrows when there is danger another gerbil will thump and the others come out to see what is wrong, that is how I alway captured previuos gerbils when they got under the floorboards but he doesnt respond to thumping
