Some will, some will not, and nobody can tell you which yours is in advance. Keeping the ball in a track removes the usual failure, which is the toy disappearing after thirty seconds. Cats that already chase things on their own tend to take to it. Cats that only play when you join in usually need a nudge to begin with.
Do cats get bored of ball track toys? Most do, which is why rotation matters more than the toy itself. Put it away for a fortnight and bring it back out and it is new again. Leave one down all year and a cat stops registering it at all.
Are 3 in 1 cat toys worth it? For the space they save, usually. On how good each part is, not always, and this is a fair example: the track is good, the scratch pad is a compromise. Judge a combination toy on whichever part you actually need.
Do scratch toys replace a scratching post? No. A pad built into a toy gives somewhere to dig in mid-game. It does not give the full body stretch a cat gets from a post, and it has nowhere near the surface area of a dedicated board or lounger.
What is the difference between a cat toy and a cat scratcher? The first occupies a cat; the second absorbs claw wear and allows a full stretch and a scent mark. Anything doing both does the second at reduced scale.
Cat activity drops sharply in households where the same two or three toys stay out all year. Three in rotation beats ten left on the floor.
