I had these growing up with past hams and I never really liked it.
It was so hard to clean and so small
One of my dwarfs figured out how to pop open the front door with his teeth! I was about 8 years old and I sat there and would close the door and a sec later he'd pop it open, id close it and we did this for several hours back and forth until my mom got home and I dont remember exactly what she did but she some how locked it in place with a lock and ties haha
