Review on Interactive Cat Treat Puzzle - Nina Ottosson By Petstages Buggin' Out Puzzle & Play: Boost Your Cat'S Playtime And Intelligence by Brian Lee

Because of the smaller size of the openings, kibble does not dispense from these toys as easily as it has from other kibble-dispensing toys I've used in the past (from a variety of manufacturers), so it took a few days for me to train my cat that there was food inside these plastic mice and how to bat at them to get the kibble to come out. (Training entailed my repeatedly getting down on the floor with her, pushing the mice with my own hands and also holding her paws to push the mice with her paws, and showing her that food was being dispensed.) Since she caught on, she has kept at them (I use all three mice for every meal, put in a variety of locations) until they disgorge all of their kibble. She seems to be getting more efficient, but it can take some time, and the owner must have the strength not give in to meowing that pleads for an easier option. :-)I don't know that all of the decoration on these mice makes any difference. Given that my cat also readily uses other kibble-dispensing toys that are quite plain, I don't think the decoration on these is making them more attractive to her. At the same time, I do appreciate that the fabric covers and the irregular shapes slow the dispensing process, as compared to plain balls.One small quality-control issue with the set I bought was that the fabric cover was misaligned on one of the three mice, so the opening was partially blocked by the fabric. I had to manipulate the tightly attached cover to unblock the opening; otherwise, it was quite difficult to get the kibble in or out.On the whole, I'm very happy with this purchase, as it adds effort and play to the feeding process.
