How it works
How does it work?
SUMU Cave is a heated sanctuary designed around how wild cats actually sleep. It's enclosed. It's warm. It's protected. When your cat enters, their nervous system gets the signal that it's finally safe to fully relax.
SUMU recreates the small cave hideaways wild cats naturally seek in nature. Your cat's instincts recognize it immediately as a true safe space.
How do I use it?
Simply place SUMU Cave in a quiet corner of your home, turn on the heating element, and let your cat discover it. Most cats enter within 24 hours because the hideaway design and warmth trigger something primal.
Your cat doesn't need instructions. Their instincts already know what to do.

Common Questions about SUMU Cave
Will my cat actually use it?
97% of cats enter SUMU Cave within 24 hours. This is because of cats' deepest instinct for enclosed and warm spaces. Your cat's instincts recognize SUMU as exactly what they've been seeking.
Most customers' biggest problem? Having to buy multiple units because their cats won't leave the first one.
Is the heating safe to leave on 24/7?
Yes, completely. The smart temperature control is calibrated to your cat's natural body temperature (102°F) and automatically adjusts based on environmental conditions. It's vet-approved and designed for continuous, safe use.
How is SUMU different from other heated cat beds?
Most cat beds are open spaces that leave cats feeling exposed and anxious. SUMU is built around how wild cats actually sleep, in small, enclosed caves. It's the first bed designed around actual cat instinct, not human guesses.
Can I wash it?
Yes. The rabbit fur lining is removable and machine washable on a gentle cycle. We recommend washing once a month to keep it fresh and ready for snuggle sessions. The heating element stays safely in the SUMU structure, only the lining comes out.
