Best Display Cases

[Twilight Pink]

Hello, what are the best types of acrylic display cases for 200+ G3 and G4 ponies? Tried looking through the internet but they're really hard to judge shelf space width with pictures.
I have 4 cats and I want to make sure my ponies are safe from them so anything with a locking door would be fantastic!
Thank you for your help
