Is there a medical reason why an other wise healthy cat would sleep all day long? He has been to the vet for general check ups and has been tested. Only thing odd about him is that his nose and paw pads are kind of dry and cracked. He sleeps all day and so soundly sometimes that I can throw things at him (not at him but I tossed a pad of paper in his direction and tossed a shirt at him and he didn't budge) and he won't wake up unless I touch him. When he is up he comes when I call him so I know he can hear. He plays and is active for the very short amount of time that he is awake. I think he is just a big lazy mellow cat. But I just was curious if anyone has some thoughts.
