It's more common than you think, and there's a clean fix. Answer a few quick questions to get a personalized recommendation for your home.

Dogs are drawn to the litter box by instinct. It's not a discipline problem. It's a natural behavior that needs a clear, consistent boundary to redirect.
The solution is not a closed door or a baby gate your cat refuses to use. It's an invisible boundary your dog learns to respect, while your cat comes and goes freely.
Micro Shields® by Invisible Fence® Brand creates a small, discreet boundary right around the litter box area. Your dog learns to stay out. Your cat never notices it's there.

For dogs, the litter box is irresistible by instinct and correcting them in the moment does not stick. Micro Shields® create a boundary around the litter box area that your dog learns to avoid every time, whether you are watching or not.

Your cat should not have to compete for access to her litter box. Shields® creates a dog-free zone your cat crosses freely while keeping your dog out completely. No doors. No blocked pathways. No stress for either pet.

Shields® pairs with Boundary Plus® outdoor containment and the Doorman™ pet door to create a complete indoor and outdoor system for your pets. Your local Invisible Fence® Brand dealer handles setup and training from day one.
