I'm looking for a way to provide my cat with some stimulation and excercise.
He's about 7-8 years old, not very old. He's on a good diet. He's neutered.
He's also half-blind. He was that way before I got him.
Every toy I get for him is ignored. All he does is eat, sleep, get pets, use the shitter, and take the occasional dash across my condo.
No way am I letting him outside. If I ever do, he's going to be on his harness and leash and under close supervision. I'm never letting my cats outside again since my childhood cat became roadkill (don't blame me for having been a stupid kid).
I'm running into the same issue with my cat. If your cat is really food motivated, maybe there are some puzzle toys you can use to hide treats in.
Sadly, I haven't been able to find any at my local Petco. I think that there may be some online.
This, OP, seeing as how your cat is half blind, then toys with interesting scents and especially toys that make interesting sounds will motivate him.
Google Homer's Odyssey, not the ancient one, the one about the completely blind cat that survived ground zero of 9/11. That book will probably give you some great ideas for helping to mentally stimulate your cat and give him plenty of exercise.
In the mean time, try getting one or two of those little bells that are basically hollow balls with a metal pin inside, like the kind you always see on reindeer. Tie that to a sturdy string with some brightly colored feathers. Or maybe a small pouch full of catnip. Then gently wiggle that around near your cat until it chimes enough to get his attention.
