Yes...I'm a designer. HOWEVER...anyone who knows me knows that I am passionate about cats (well...all animals, actually but cats most especially). Sooooo...my youngest cat Walle and his brothers are going to review cat toys from time to time.
Here's Walle:
Walle's name could actually be Butch because he's very tough and rambunctious. If a toy can be broken, he'll break it. I've spoken of Walle here and here and here. Oh yes, and here.
First toy is: UNDERCOVER MOUSE by Panic Mouse
Depending upon where you buy it, it can be a little pricey...anywhere from $15 - $30..ON SALE! Its original price is listed at mega bucks more than that. We got ours on clearance at the pet store for $10.
Two paws up for the box it came in! AND, Walle loved the paper with the instructions and basically everything that came out of the box even though he had no clue what it was or what it could do.

Walle decided to help my husband put the toy together. Thank heavens cats don't understand four letter words because his help was NOT appreciated.
Not wanting to use up any lives unnecessarily, he decided to wait patiently. And then...
TA DA! A word about how this toy operates. There's a round fabric circle you place over a battery operated motor that has a wand attached to it. This wand has a little red tail hanging from it. The wand goes round and round under the fabric with the red tail sticking out (at different speeds depending on how you set it) and basically drives your cat nuts.

I've got to say, even Opie (on the left in above picture), who is often a little "above" playing with toys, found this toy pretty amazing. Rudy, the redhead, is equally entranced.
Bottom line. Walle loves this toy. AND about a week into playing with it, he broke it. If a cat could cry, he did. Let me tell you...whew. Soooooo...I got some duct tape and taped the wand back together and we're still going strong three weeks after purchase. Thank heavens for duct tape. By the way, we don't leave the toy down all the time...I notice other reviewers mentioned their cats got sick of it. It's a once a day treat for about a half hour.
Enjoyment factor: 4 paws up
Durability: 1 paw up
Walle says: "buy this toy along with some duct tape"
Debra says: "if you have to pay full price ($30 or more) don't get it...your cat won't mourn what he doesn't know exists. If your cat is hard on toys and you're willing to repair it, then go for it."
So, grab it on a good sale over at Amazon. Or google it and find an even better price. Then go buy some duct tape and watch your cat have some fun.
