I think while she can still enjoy the sun and she is eating I would let her enjoy this beautiful weather, buy her whatever she like to eat best and spoil her rotten.
I love this poem, though it is very sad.
A 14-YEAR OLD CONVALESCENT CAT IN THE WINTER
By
Gavin Ewart
I want him to have another living summer,
to lie in the sun and enjoy the douceur de vivre ?
because the sun, like golden rum in a rummer,
is what makes an idle cat un tout petit peu ivre ?
I want him to lie stretched out, contented,
revelling in the heat, his fur all dry and warm,
an Old Age Pensioner, retired, resented
by no one, and happinesses in a beelike swarm
to settle on him ? postponed for another season
that last fated hateful journey to the vet
from which there is no return (and age the reason),
which must soon come ? as I cannot forget.
You will know when it is the right time, I always think the light goes out of an animals eyes when they no longer want to be here.
Hugs to you, it is so hard to watch them very ill when you know that they will not last much longer
