This is poorly made product. The mice is rock hard so if you step on it - you will get hurt, for sure (I sure did!).

Our kitties do not care for it either.

I like the quality of the cage, BUT be very careful!!  My poor little kitty cat got his paw stuck in the wire and cried his eyes out until I could free him.  It took me about 30 seconds, and his paw was swollen and sore.  He is now a little afraid to go inside.

I would recommend to the the manufacturer to make this item safer for cats.  I would be very sad if someone's animal died from this happening to them.

Not good for older cats. My cat had this collar when he was 6 or 7 and had no problems, so I thought I'd try it again (he's 12 now.) Huge mistake. Within 24 hours all of the fur on his neck had burned off and the exposed skin was bright red and shiny. I took him to the vet and the vet said that this needs to be used on younger pets with no break in treatment, i.e., must be used continuously or there is a higher risk of this happening. Spent more money than I intended and will try something else

Terrible toys. The cats destroyed within 2 minutes and almost eat the materials that seem to be made of a pretty toxic foam and could endanger your cats health if ingested, obstructing their intestines to say the least. Do not buy this product is a hazard. So bummed because I bought it because it was Jackson Galaxy product but he totally gave him self a bad rep endorsing such horrible and potentially harmful product for Cat....

The reviews look promising but I'm uncomfortable using it on my cat, as she grooms herself and nonoxynol-10 is disruptive to the endocrine system. I will search for something else.

I gave this to my 3 cats. One of which immediately started having anal leakage with a very fowl odor. They all scratched so hard they lost fur, one was so bad he has severe wounds and fur loss. The other us seemingly ok other than fur loss on the back of the neck. I keep reading about other horror stories and now severely regret purchasing 1 years worth for each cat. Do not buy this product. Spend the money on frontline or advantage.

It irritated my cat's eye. Do not use on eyes that have wound. I tried on myself also and it burns!

BEWARE -TERRIBLE HARMFUL PRODUCT!!  I bought the Purrfect Arch from Amazon 10/29/14. Cats love the bristles, but the BRISTLES ARE NOT SECURED IN STEEL SPIRAL. CAT CAN EASILY PULL BRISTLES OUT WITH TEETH AND SWALLOW THEM, CAUSING SERIOUS INJURY, EXPENSIVE SURGERY, CHOKING OR DEATH.  If bristles make it into back of throat or esophagus, cat can panic and choke. You will not be able to pull the bristles out and have to go to the emergency vet  very scary, expensive and potentially FATAL FOR CAT. DO NOT BUY!
I had one of these arches by another manufacture for years for my previous cats and they loved it, the bristles could not come out and it worked perfectly. Like many other things outsourced to the cheapest manufacturer, the quality has gone to zero.
If you can pull the bristles out with your fingers, your cat can pull them out with his teeth. Take the Arch away and demand a refund, no matter how long it has been.
IF YOUR BELOVED CAT IS INJURED BY THIS TERRIBLE PRODUCT, SUE THE MANUFACTUER!!!

Wish I had read more of the BAD reviews before purchasing. My cat is violently ill and being taken to the vet today and after sitting down and reading the BAD reviews I know exactly why. I feel like an idiot.
  I used the treatment AS DIRECTED EXACTLY.  My cat went crazy trying to get away from me. He has never liked me messing with his ears so I thought it was because I was doing that very thing. This was in the evening. Next morning he had vertigo and turned down breakfast. NEVER has he turned down his soft food. I feed an extremely palatable canned dog food that my cats want more than their own canned food so I tried that. No luck. He is drinking but no appetite. I did this Wednesday night and Saturday morning he ate about a TSP total. I am going to treat him with activated charcoal because I believe he has been poisoned. I am deeply regretting this STUPID purchase. The second I smelled the odor I SHOULD have known better. If the activated charcoal doesn't do the trick he's off to the vet Monday. I WILL be requesting a FULL REFUND from Amazon and also making SURE that in the future I pay closer attention to the negative reviews instead of the more positive. I'm happy for those that were able to use this product successfully but I wouldn't recommend trying unless you have the money for the vet. I rescued him from dying as an infant just to kill him from my own stupidity?!?! BUYER BEWARE....=(

Do not use this, unless you want liter all over Your Home and clumped to your cats paws and fur. The only plus is that its physicaly easier to lift. Otherwise, I found my poor cat with liter COVERING his hind legs. He was trying to clean them, and I cant imagine how much liter he infested before I found him and had to clean them myself. Not worth the weight at all

Rec'v this today. My 2 cats literally hate my help for fleas. Scratch, bite me, etc. Once I tried this on my male, he was purring and actually let me rub it on him. He sniffed it a couple of time and moved around to help me rub it on him. Based on his response, i would say it a Great. Haven't tried on it on the female yet. Got my fingers crossed
I have to change my rating. Two wipes over 2 days. My female is gone. Apparently not all felines are able to handle peppermint oil. I blame myself. I read the good reviews and didn't check further. Peppermint is on the TOXIN list for many felines.
Natural does not mean it's fine for cats. It depends on the cat. While I'm talking to an emergency vet at 1 am, they said call  Poison Control for more info. I bought a product to bring comfort to my pets. I now have to cremate one.
Hartz flea treatment also kills your baby. BE a educated parent. ONLY buy through your Vet Doctor. It may cost more, but you won't be burying your baby

Make sure you do not put these on an outdoor cat and please please make sure you monitor your cat while it is wearing this collar!! These collars do not have a breakaway feature and when I bought them for my indoor car I didn't think that would be an issue. Turns out I was wrong!!! I came home one day to find my cat relatively limp and lethargic on the floor pawing at her face. I grabbed her and find she had the collar stuck in her mouth while also still around her neck. So her mouth is stuck open, drool pouring out, and she is panting like I've never heard before. It was terrifying. And keep in mind I put the collar on her pretty tight because I didn't want her to get caught on anything in the house, terrible mistake. Thankfully she was okay. So if you're going to buy this collar and you think your cat will try to get it kff, please watch them closely while they're wearing it!!! That being said, when it wasn't chocking my cat to death, it did work very well to calm her down. She stopped pawing at our door in the middle of the night!

This product made my cat terribly ill. Could have killed him. Caused him to make crystals in his urine which could have blocked him leading to surgery or death. Ended up costing me over $100 to treat him. He never had any health problems on Royal Canin. Switching back.

My cat has a granuloma on her abdomen and Vetericyn did nothing that I could see to alleviate the discomfort or promote the healing.  It was surgically debrided and vetericyn is not helping.  For all I know I could just be spraying water on it.

I got this collar for my cat but I didn't want to put the collar directly on the cat. The collar is not a safety breakaway and I get very worried about leaving collars like that on my kitten. We got this collar to help the other cats in the house get used to her though and it did that although we slightly modified it. We cut off a section of the calming collar and sewed it onto the back of a normal breakaway collar. This worked great and it also means the collar lasts much longer. I still wouldn't recommend these for anyone though unless they were going to modify them like I did because they could be very dangerous for a cat.

DO NOT use this for cats. If one bit of it comes off the couch it will all come off. If it gets attached to your cats fur it will peel off and it will force you to cut it off. It became wrapped on itself around our cats tail and was impossible to remove without clipping fur. Poor cat was upset for how long it took to remove and the hair pulling the ensued.

As of now the description mentions as a cat deterrent. I hope they remove this because if I wasn't present it could have been worse. The cat could have been injured or more upset with us.

I gave it two stars because I am sure I can re-purpose it for its intended use as a carpet/rug tape. I will never ever use it again for cat deterrent again ever. Trust your gut on this one and avoid it. If anything go with a tape designed for cat deterrents. This is just a problem waiting to happen.
