I noticed the other day that there was a scabby area on Bugs' back and wondered if one of the other cats had bitten him, then we noticed a couple of fleas in the water bowl (Although I couldn't find ANY flea dirt on any of the animals!!???) so I took him to work for a steroid injection and flea treatment thinking he must have flea allergic dermatitis. NOW I have finally figured out what is the matter... Each night he goes up onto my front room window and goes to sleep, he often all of a sudden falls off the radiator for no apparent reason. Tonight after a fall he started licking what had been an nicely healing area but I noticed it was bright red and REALLY sore again. Reason... the radiator was on and it is just where his back contacts the radiator as he falls into a deep sleep so I think he must be burning himself really badly bless him!!! I have just applied some fucidin to the burn and placed a blanket over the top of the radiator to prevent him doing it anymore. I feel really bad for him though as it must be blooming painful and he loves sleeping up on the windowsill so for him to suddenly have a searing pain whilst asleep must be so awful and confusing to him!!
