I found this cool chastity device that pops in where the lock goes and its impossible to remove without breaking something. Im so tempted to buy it so I cant cheat and take my cage off anymore.

I'm probably being old and cynical, but if the cage is plastic (eg Cherry-Keeper) then removal is simple, whatever the lock. OK, you must damage the device, but there is little risk of injury. So just use a standard lock and throw away any keys.

Or get a stainless steel device, a decent lock, and do the same thing with the keys. That will be a lot nearer permanent.
