Hello, my friend. May the Lord grant you a great life and good health. I can tell you have a good heart toward living things. Rocky would mot have made it so long had it not been for your love and care. A cat or dog has to CARE and if they cease to do so, then their life is cut short. I have a fifteen year old kitty, a female named "Erin" (after hurricane Erin in 1995. The hurricane had just made landfall in the Gulf when we got Erin from the Humane Society. She had been born in a barn...) AKA "the Mouser", although she's never even seen a mouse; it's because of her pretty, mousy gray color. The Mouser is happy because she's much loved, even though she's a bit on the persnickety side at times; I bear with her because it's just the way she is.
I believe Rocky can live a few more years than he has, so long as he is continued to be loved and tummy-rubbed and all the little special things you can do to show him he is loved and special. Some special, little toys can often perk up a kitty. I've had kitties since I was nine years old and fifty years have passed since then (hard to believe) and I've gained a fair amount of insight since then. God has put certain animals on this earth for our mutual love and pleasure. My life, the last twenty-one years spent in disability and pain, has been much improved because of my love for the Creator's animals, although my grief is very heavy when I lose one. I just take it really hard. Thus far, even at Erin's age, she can still scat about the house with the big male kitty we have ("Tweeder") and in fact, can lay a fair-sized whuppin' on him if he gets out of line and he outweighs her by a good six or seven pounds.
Well, I've rambled. It's my wish that you have many more years with Rocky, as a HEALTHY kitty. May his health improve and his temperament show it. May his joints loosen up and may he feel freer that he has in many years. This is my blessing for your Rocky kitty.
And may you be happy and live a long, productive and special life in God, apart from Whom there is little to even hold dear.
Take care, my friend.
My love to all,
