Poor little fighter has gone.
Well, our little temporalis guy passed away today, about 5 hours after I gave him his daily treatment. I wondered if he was on his way out, he just looked so miserable. Poor little guy. It is sort of a relief. He's no longer suffering.
We didn't euthanize him, he just went on his own. Wish I could have taken him to the vet.
Thank you, everyone, for your help and advice and PMs.
