    This cage is the first upper end cage I’ve bought, and it did not disappoint. I really appreciate how it balances enclosure and access: I have enough space to clean it fairly thoroughly while wearing it but still enough coverage to get that enclosed/lack of access feeling that makes long term play so fun. The security screw system works great to keep things sleek and quiet. The punishment pins are fun and engaging, and work great (medium and long both are present when not aroused and deterrents when aroused, I don’t get much from the smalls but your milage may vary).

    One of my biggest problems with cages I’ve tried in the past is testicular slippage through the ball trap ring. With my Pet Trap, I got the oval rings with the small gap, and I haven’t had a single problem. This is the first cage I’ve ever owned where I feel safe and confident leaving the house without the emergency key on my person so I can fix a ball slip.

    Highly recommend, thank you to MM for creating this beautiful piece of art. I love this piece and would tell anyone looking to upgrade their cage that MM are fantastic to work with.

    After two weeks 24/7 wearing the Pet Trap, this has become my new favorite of the several chastity pieces I have. It has been totally comfortable, except for the occasions when I am teased and it does it’s job; then it’s pretty frustrating not to be able to do something about it. As the days have gone on, this has become more of a challenge, much to my keyholder’s delight. Though the cage has more metal than the Jail Bird or Queen’s Keep, the slots on the top and sides allow space for pulling the skin back for cleaning. We ordered the cage a half inch longer with the vertical bars on the outside, so there is only an occasional pinch. The security screw is a great option to eliminate the bulk and noise of a padlock. I haven’t had any problems with the screw loosening as some have reported, but I also gave it extra torque when putting it in. It is so hot being securely encased in this beautifully-made piece, knowing that someone else holds the key and that the time of my release is dependent on her decision.

    I love this device! Or do I hate it? Both I guess. After getting tired of breaking plastic devices, uncomfortable pinching, floppy padlocks, and the feeling of knowing I was not as secure as I really wanted to be, we got this. And it’s great. I am a bit of a tinkerer and have modified this myself with a couple extra cross bars at the tip for more security and screw in spikes down the shaft. Whatever I own I gotta customize it and make it mine but this was great the day we received it. With the high security screw and anti pullout it’s so secure. And it feels it. It’s the perfect weight and is nothing like plastic. The strong downward curve really prevents erections and any chance of shaking your cage to get off like some plastic tubes. I wear it 24/7 for months at a time and have never had an issue of any kind. I don’t imagine I’ll ever need another device.

    My Master wanted me to buy this after he had caught me pleasuring myself. I was a bit skeptical, as I’ve had other devices before that were either uncomfortable, or came off too easily. This is neither! It’s great, and both Master and I are exceedingly happy with it.

  5. Morgan’s slave

    I have been locked in the Pet trap for nearly 500 days (it’s true). There is no chance of getting out of it without Mistress Morgan using the key. It is perfectly secure. comfortable to wear (except when suffering Morning Wood) and hygiene is not a problem. It drives me to distraction sometimes but of course that is it’s purpose. I had a series of plastic cages before, all of which broke. This is just perfect.

  6. Locked-up

    And it won’t be my last! Just like the Watchful Mistress, the craftsmanship is second to none. Perfect for daily wear (24/7/365). After a while you can’t even tell it’s there. If you’re going to get a custom device, don’t spend thousands of dollars on one device from some of the other online retailers. MM’s devices are reasonably priced and better than anything you’ll find! I’ve owned almost a dozen devices from the CB series to whatever is on Amazon or eBay. The last two I’ve bought were from MM and it will be the only kind I buy from now on.
