Last July we lost Skipper who was just about 7 years old or so, Deb brought him in after he was bitten by something outside, and the vet said he had cellulitis and certainly would have died had he not gotten help. Last year, he just started crying for reasons we could not understand, we took him that same night to the vets who ran tests and couldn't really find anything, but gave him an antibiotic shot because he had a history of UTI's and we took him home, only to come home from work the next day to find him dead. We suspect what happened to him years earlier, being bitten and sick, may have shortened his lifespan, perhaps the same happened here. But they both had wonderful lives full of love and food and shelter and comfort, and someone told me when he passed "it's better to have a good short life than a long bad one".
