EDIT: I wanted to come back and leave some more info on this review. We've had this puzzle for years now and it has held up amazingly. It's very durable. It's still by far the best cat food puzzle I've ever purchased and we use it almost daily. I recommend it regularly to all my friends and coworkers who have cats.My two kittens are absolute food fiends. we've tried multiple food puzzles but many of them were unsuited for young cats, and the kittens injured themselves by using their muzzles to get the kibble out rather than their paws. The large plastic shell on this puzzle makes it impossible for them to access food by any route other than using their paws, which is just what I wanted. And the adjustable layout is great for young cats because you can start out easy and then ramp the difficulty up. The only downside was that the plastic shell doesn't clip on very securely, but as you can see in the photo I was able to thread some zip ties through the bottom part and around the shell to keep it firmly attached. I have to cut off the zip ties every time I want to wash it or change the layout, but other than that it works great. Now we can eat our food in peace without our cats trying to steal bites from our plates!

For the "classic" puzzle:Awesome treat puzzle, the customizable obstacles are going to be great to change it up a bit to keep it engaging. A clever cat will master it quickly but it's a good challenge regardless.The two things I wish were different are:1. The two tall arch pieces are very limited in where theu can fit, because for some reason they have a tab to stick out of the clear cover. This does not help them support the dome, so i dont see any reason for the tabs at all. I might be able to modify them by cutting off the tab to allow the arches to fit under other parts of the dome.2. In the pictured product, all of the peg holes appear to be the same size. This is not the case in reality. There are two holes on each end that are too large to hold any of the obstacles, and also large enough that pieces of my cat's food can fall through the puzzle onto the floor, which is frustrating for the cat when she loses them. I'm planning to permanently fill or cover the large holes.Other than those two modifications i need to make, it's great. Engaging for the cat, easy to clean because it can be fully disassembled with very little effort, just has some weird design choices.

I have a rescue kitty that is part Savannah. Therefore, she has a very high prey drive and is highly intelligent, getting bored and depressed when she has nothing to stimulate her brain. I bought this for her and she LOVES it!We also have her sister, who is out of a different father. So while both have the Maine Coon from momma, sis has more Persian/HImalayan than the Savannah that Honey has. As a result, Sis prefers to just stick her nose in the bowl and eat--forget about the games! But even with a bowl down and available, Honey will go to her puzzle feeder and play with trying to get food out of it.The fact that you can rearrange/remove/add obstacles is nice as it helps to keep her thinking with new challenges occasionally. She really enjoys that and feels better with something to challenge her mentally.The whole thing is plastic and easy to clean. The lid does allow for kibble to fall down in between the walls and the lid though, so every couple of days you have to remove the lid and clean up all the old kibble that has fallen down where she cannot reach it. Maybe that is something they should rethink and come up with a different way of seating the lid to prevent kibble loss.It does stick pretty well to the tile floor, although she can move it when she pushes against it to try and get to the pieces that have fallen down between the lid and outer wall. It has never flipped over though, even when a 16 pound kitty running full tilt has lost footing on the tile floor and slid into it, knocking it a couple of feet away.Overall, it is a big hit with the kitty. She loves it and it keeps her happy, challenged, and occupied. That makes me happy, along with the easy clean up. Good price and good value for the price. If you have a smart kitty who is easily bored because they are not challenged enough, I would definitely recommend this as a try. If you have a porky pig like her sister who prefers to just stick her nose in the bowl and not come up for air until the bowl is clean, then perhaps not so much.

I have a very VERY active young cat (was a kitten when I got this, still a ball of energy now) that absolutely loves to get into anything and everything. I also have a sweet elderly cat that isn't interested in most toys (would rather bat at something once and call it a day). Both of them love this treat maze! I've had this for roughly two years now and it still remains a favorite for both of them!! I only use it for putting treats in and not having it out all the time to keep it more special.They both seem equally engaged with it, it isn't too hard to fit paws in for my elder cat with arthritis, and it holds up to the chunky young adult (12ish pounds) that likes to play aggressively with his toys. He can drag it halfway across the room and the top doesn't come off. In fact, usually it stays mostly in place, it will move a little bit especially when they're both working on the same side, but unless he's going all out it'll stay in the general area I put it. If it was just my elder cat, I'm sure it would stay where I put it down. I have also accidentally kicked it a couple times and absolutely nothing happens to it.The quality of it is great. I love that I can customize the inside maze part and I think they enjoy having it change from time to time for a new challenge. It isn't super hard for them, but also not too easy and boring. Usually they'll get the easy treats out first in just a couple minutes, and then they'll be working at the hard to get to spots for a while. It will entertain them for at least 15 minutes, sometimes up to a half hour.Literally my only downside to this is on occasion a treat gets stuck and wedged under one of the maze walls. It's not that big of a deal, easy to dig out with a hand, but the cats are not able to get a wedged treat out no matter how long they work at it. (But hey, if you want your cat to stay busy for a long while just wedge a treat haha)It cleans easy. All the maze walls can be taken out and the base is a hard plastic with the green part being a thick rubber sort of material. Some soap and water and it's all clean, no spots for treats to get lost in and attract unwanted pests.I would recommend for any cat, active or not (this is one of the few toys that my elder cat wants to play with), and as long as they like treats they'll like this. It does a wonderful job at being an interactive toy for them.
