Ask a Cat Question, Get an Answer ASAP!
Sorry to hear that Leon is having issues with his tail. It sounds as though he has hurt his tail. Sometimes this can be caused by getting the tail trapped in something and having it pulled (a tail pull injury) which can cause damage at the base of the tail. It also may be due to a hit to the tail or a bite from another cat. Cat bites can cause abscessation sometimes at the base of the tail which is very painful. If the tail is limp it does suggest that he possibly may have caused quite severe damage. If he looks down or sad then It suggests he is in quite a lot of discomfort. I would recommend him seeing a vet today so that they can examine him fully, prescribe pain medications and anti-inflammtories or antibiotics if required. He may also need to have X-rays taken of his pelvis and tail to check for any fracture or damage. I would contact them ASAP to arrange for an appointment.
