Best for
It suits larger cats, homes with multiple cats, and owners who want automatic cleaning without asking a nervous cat to enter a tight enclosure.

The open-top design is the reason to consider the M1 Plus. It can feel less restrictive for larger cats or cats that hesitate at enclosed entrances, while the generous shape makes it a practical option for multi-cat households.
