Herman, our cat who is no longer with us, absolutely loved smelly feet and shoes. He would put his muzzle down inside shoes and fall asleep! The stinkier the better! We have one photo of him with his paw inside my dad's shoe. Dad was asleep on a patio chair with Herman asleep right at Dad's feet. We used that picture at my Dad's memorial service. When it came on the screen, everyone chuckled. What a great stress reliever! Both were characters and I miss them both.
