My lovely cat is coming up to 15.
He doesn't go outside much any more and he doesn't venture upstairs very often either.
He spends most of his time curled up on the kitchen doormat, sleeping.
He still washes himself and has a beautifully groomed coat.
He has the same healthy appetite (3 pouches of wet food per day).
But he doesn't go out on adventures or get up to greet me when I get home, or even seek out other spots in the house to sleep in.
Is this normal? Should I be looking out for any signs of illness or distress at this age?
