I noticed my giant was incontinent when she kept having accidents in her cage even though she was housebroken (she was only a few months old at the time). At first I thought it was maybe she just couldn't hold her urine, but then she had an accident while she was at sleeping by my feet...she did not even awaken when she had the accident!! When I took her to the vet they suspected an urinary infection and treated her for it. However, it did not "fix" the problem. She has since been put on Proin 50 tablets (I think it is PPA?) and that seems to take care of the problem for the most part. I have heard from some that she MAY outgrow this, but was just curious as to why so MANY giants seem to have this problem.
