It made me wonder if kitty wouldn’t be more comfortable in a nice snug carrier, to help with the overstimulation. One of our cats had kind of outgrown his carrier, he still fit but he couldn’t really move around much. The vet noticed and made a point of saying that they actually benefit from the smallness when they’re going through stress, like car rides.
Everything about that beaver reminds me of the folks who would crash our workplace’s massive, Thanksgiving pot-luck lunches. That especially includes the super obvious walk-off with the food. People would stare; chowhounds wouldn’t care.
