    Fits adult mouse

    Posted by Abby on 10th Sep 2021

    This fits my little pet mouse great, he just really hates wearing it. I can’t have him wear it all the time because he can’t really pick up food and eat it when the cone is on, but I put it on him for a little while a day to let his skin get a break. He has a stubborn addictive scratching problem.

    Not for guinea pigs

    Posted by Lori M on 13th May 2021

    I bought the large size (and a size smaller just in case) and they are way to small for my little guinea pig. Even if they did she would still be able to reach the surgical site on her back leg.

    This worked great!

    Posted by Jane on 31st Mar 2021

    I got a couple of these because I always end up with squirrel babies who are “suckers”. I thought I’d try this. It works great!

    Completely ineffective for squirrels

    Posted by Rachael Varga on 28th Aug 2019

    My 500g squirrel had surgery and wouldn't leave his incision alone. He had an ecollar on from Amazon that works great but he can't hold food to his face. I bought this collar hoping he could eat better. I bought medium and large because both say they fit squirrels. The large fit (it would not have fit either of my rabbits) but the diameter of the collar isn't large enough, he had more than enough reach to self mutilate and open his surgery site in minutes. He's now back in his tiny cone from Amazon and at least a week regressed in his healing.

    Great for Pet Mouse

    Posted by Ayla Eberly on 31st Jul 2019

    Worked great for keeping my pet mouse from scratching himself bloody due to a currently unknown cause. Was scratching ears, face, and back of the neck, and now his wounds are finally able to heal. He's semi-hairless and after one week there has been no abrasion of the skin due to the collar.

    It's exactly what I needed for my mouse but I just can't figure out how to put it on. She just squirms and I'm desperate

    Mouse self-mutilation finally healing

    Posted by Unknown on 9th Jul 2018

    Used this collar on my pet mouse to allow a mite-turned-self-mutilation wound to heal up. She doesn't love it, but is able to eat and drink regularly (a little sad to see her bracing her hands on the cone trying to hold her food...). Only one time was she able to get it off by herself, but I tightened it a little and no further problem. It has worn the hair off around her neck a little, but it doesn't look too irritated. I've been giving her ~30 mins of supervised cone-free time every day and she seems to be doing better!

    Henry's Response: We are so happy to hear your mousie is healing!

    e collar

    Posted by Unknown on 17th Nov 2016

    As a wildlife rehabber I did not know there was such a thing. It will be the perfect solution for reducing the risk of sores and injuries being chewed on...

    Awesome collar... But can you make the same collar with a larger diameter?

    Posted by Jamai on 21st Sep 2011

    I have used this collar on a squirrel that is chewing on the bottom of his legs. It is very easy to use, and I would highly recommend it for anyone needing an e-collar. However, my squirrel eventually figured out how to straighten his leg and fold the collar into his belly so he could get to his legs to chew.

    I hope if the owners of the site are reading this review... I would absolutely love to be able to purchase an e-collar with the same neck size but a larger diameter. (In the end, I had to cut out hard plastic and staple it to the e-collar to increase the diameter enough to stop him from chewing.)

    Thanks for considering my input!!

    [Answer from company: The size we carry works well for most squirrels; however, chronic self-chewers will eventually figure out how to defeat most collars. Sometimes a "homemade" collar works best in those cases. There are other styles and sizes of collars available at various pet stores, including a new inflatable one. Best wishes for the recovery of your squirrel; please let us know if there's anything else we can do.]
