Recommendations for cat puzzle food board for older cats

[mathsfiend1]

Our vet suggested getting one of these to keep the cats' minds active - does anyone have one their cat plays with and can recommend? Thanks.

no, but this sounds interesting. following for interest....
My cat is extra senior (19) with arthritis, so not interested in chasing his "batting balls" anymore. I do worry that he gets bored. Especially as he is too scared to go out in the garden now :(

I got both of these, but the cat ignores them both and miows he is hungry
