When is it kinder to pts? He's at least 18, been deaf for years, now his sight is limited (and getting worse) and his back legs are wobbly.
He gingerly walks round our garden (mostly in circles) and is very vocal and yowl-y.
He is still keen to eat and drink.
He has to sleep in the kitchen as its the only tiled floor on the ground floor -he can't manage stairs and will wee wherever he happens to be.
He has been ok over the summer as he likes snoozing in the sun but I'm thinking now his quality of life is not what it should be for a former mighty hunter 
I made the decision for his bro 4 years ago but he was obviously sick whereas Boris is just old...
