I'm looking for suggestions as to toys with a puzzle element that DCat might like. Ideally not involving food, as she's a rescue and we've had some difficulties to work through so don't want to introduce a new element to a routine that's working.
A recent favourite toy has been a ball of silver foil that she'd happily bat away and then chase around, or play catch or hide-and-seek with me. At one point, it was under a plastic packaging box, which fascinated her but she's managed to work out how to tip that up to get the ball out so has lost interest now she's “solved“ it.
Any suggestions for toys or puzzles that are easy to make at home or not too expensive to purchase please?
