I've noticed a few times recently that when I've checked Gismo's bottom that the fur around there and his back legs has been wet with wee. He's only a short guy so I wondered if he just can't get his bottom up very high. Also I recently put down some vinyl tiles in their main living area and stopped putting down wood shavings because he had slightly sore hocks and I thought it might of been irritating him but maybe then he wees there and ends up soaking it up?? Is there anything I should be worried about? He seems fine in himself in all other ways.
