Rocco has started not wanting to cross the kitchen floor. This just started happening within a few days. His food and water are in the kitchen and he goes potty out the back door. He will walk about a foot into the kitchen and not want to go further. We haven't changed anything to make that be the issue. Our kitchen is the pergo floor and we have carpet in the living room, which connects to the kitchen. Last night he had me lift up the octagon to walk through the kitchen. Any ideas on this behavior?
