The cat toy is this, recommended somewhere:
It moves the toy around in random-seeming bursts. Has two speeds besides "off". If I use it sparingly, I think he's gonna be into it for a while. It's good to have variety with this guy.
The other recent experimental purchase I got, I haven't tried out yet. It's a magnetic closure for necklaces, so I won't have to fumble with the hooks for forever, with my very short nails and high level of frustration and low level of necklace donning experience, for my age.
I went with the 3-pack, thinking that'd be pretty good for starters, if it seems to work. There are probably only 5 necklaces I wear with any frequency at all, not counting some long enough I can just put 'em over my head. And 2 of those are bow tie cop-outs.
