Pros
-Measures food accurately
-Long battery life
-Great for when out of town for multiple days

Cons
-My cats have learned 2 methods for getting food out on their own. They bump it, which spills bits of food, or they reach up into the feeder and pull food out. This is a serious design flaw that needs to be addressed. Instead of getting a good night's sleep I can hear my cats pawing at the machine all night
-No AC adapter included (Seriously? Even for $130?)

Crazy cats! All of them! I love them, but throw catnip on a bed of nails? They'll sleep on it. Crazy cats. My in-laws and wife giggle at this when the cats just won't sleep anywhere else. Hey, I did good!

The cats get into some serious scratching with this device, and they like the sounds of claws against brand new cardboard.  One cat will sleep on it, but the best recommendation is that our demon cat stopped clawing the carpet and will go straight to the new scratchers.  I bought 3 and spread them around the areas where she gets feisty.  Now we're both happy when she satisfies her animal instincts.  I will buy more of these.

Too noisy. The cats were more interested in the origin because of the noise. Quieter ones that I've purchased from other manufacturers were quieter and the cats would ignore the origin and go after the light.

Whenever I wear this shirt I suddenly feel more powerful. I gain the ferocity and confidence of the cat. Its laser powers seep into my core and reflect stunning beams of light. Nowadays, I have found my new place on top of the refrigirator. Coiled up against the wall. Being as I am a cat now, I must act as such. I spend my days napping in the window and dragging in small critters for you to eat whispering softly to the mice "Little mouse, the more you struggle, the slower you'll die." And all you hear is affectionate vocalizations. If you get a new spouse, I'll defecate on their pillow for the eternity of their presence. If you bring a mate home, I will sit at the foot of your bed and stare eerily up to watch your relations. If you touch my belly, I'll tear your flesh off. 4am I'm up you're up. Harness the power with this shirt. Meow.

My cats like it. 5 out of our 6 cats are social, and like to play. I frequently rotate different toys...Da Bird, Neko Flies, Da Bird Cat Catcher, Cat Charmer, a hand-held laser pointer.  It initially took them almost a half an hour to warm up to it.  They were curious about the noise.  A few of them were up too close, trying to figure it out.  But now that they have, they take turns running around like mad cats. One gets tired, another jumps in.

A little in the morning before I leave for work, a little in the evening to tire them out.  Not a substitute for those other toys, just an addition to the rotation.

As I sit and watch my children at play, I'm beginning to believe that the clunky-sounding nature of this toy is, perhaps, to continue to draw their attention to it.  Maybe not a mistake by the company, but still a little noisy.

This Thing Which Should Not Be is so adorable.  He sleeps in my bed with my teddy bear, who suddenly seems fearful, and my cats who have bee meowing in odd unison.  I think the mewing probably has something to do with all the cultists chanting around my bed.  It's OK, I find chanting relaxing.

These are great to sleep on.  I had one but the cat decided it was fun to scoot around the sides of it by digging it it's claws.  You can guess the rest.

I bought this fan to drown out the sound of my cats yowling on the other side of my bedroom door all night long.  Maybe not the most typical fan purchase reason, but WOW!  I discovered in no time that I love the feeling of cool air blowing on me all night long.  Pretty sure if my cats suddenly fell silent (hey, I can dream, right?) that I would still use this fan every night.  It's very easy to assemble and just works great.  I'm happy with this purchase!

We have 2 cats and I received these yesterday - they were fighting over who got to lay on the pad in the living room so we put a second one out in our bedroom...this is the first night in over 2 years that I haven't had my cat crawling all over me at night (which I don't mind too much).  I could not believe when I woke up and she was laying on the ottoman at the foot of our bed and not under the covers on my legs!!! Our other kitty was laying on the one in the living room.  These things are magic.

The only thing I would mention is that I ordered two of these and there are two pads in each pack so we ended up with 4...not that it's a bad thing because they love them but I didn't see where that was mentioned.

Also, they aren't very attractive but they love them.  Hope your kitties love them as much as mine!!

I love this thing. I purchased mine through Petco in an attempt to correct my cat's bad behaviors.  He would wake me up at 3 in the morning pawing on the blinds trying to get outside, claw at the furniture and occasionally become aggressive.  One quick press of the button, even if I am in another room, causes him to instantly stop his annoying behaviors!  This thing has definitely allowed me to get better sleep.  A great device for cats with behavioral problems!

The cats are loving this. I ended up buying a second one because they kept fighting over who gets to sleep in it. I haven't actually closed the cats in and taken them anywhere in these, but I strongly suspect they will be much more relaxed in these versus the old carriers since their smells are all over these.

The door kept me up all night with cats going in, out, and pawing at the door.  This door is squeaky and usually bangs around on the plastic frame unless your installation is perfect.  I used a file to remove the interference between the flap and the frame and I put a drop of grease in the hinges and now the door is perfectly silent!

I have 2 of these trees one on each side of my bed. The cats take turns sleeping in my bed and the tree. I no longer have to get up in the middle of the night to make room for another cat. There is now enough room for all 5 cats and myself and I can get a good night's sleep.

Even the dogs are sleeping better - I have started leaving the babbling brook going through the day, and when I am gone, I don't think the dogs or the cat move from their spots.

I preferred to keep our cat in at night.  But I gave in.  She now sleeps in the garage.  I was very surprised to see her in her new home that I built and laying on her bed warmer.  This at least makes me feel a little better that she has a warm bed.  I have it on a timer.

This product is good... I wouldn't say great only because my cats lose interest pretty quickly and the sound goes on indefinitely.  I'd rate it a 5-star if it turned itself off after 10 minutes or so.
