Product has declined in quality
I bought a second mouse after my cat decided to drop her first in her water bowl where it remained overnight. The second one is much lighter and weaker smelling than the first one was (which was a really pungent smell, but attracted my cat for sure). She's not very interested in it at all.
I can only assume costs have been cut and this isn't as good a quality product now - a shame because it's hard to find things my cat (not into catnip) likes.
