Helping cats is tricky. They are not so docile as they can choose to be. They are on constant alert not to be eaten, even by their owners. Trust is defined only to a point. Which, given the vagaries of human nature, is probably insightful.
At one of our vets years ago, there was a vet tech named Tabitha who also worked with horses. She never explained anything, but apparently had mastered keeping her mind in a certain place, and thus emitting bodily chemicals that conveyed this to animals.
Our cat, mostly sweet natured, went into full battle mode when having her claws trimmed, screaming and assuming the face of an enraged devil, so you could hear her outside the building.
But not with Tabitha. Who sat down in the waiting area, put the cat on her lap, and with the serenity of a Buddhist monk, trimmed the nails without the slightest protest from the cat.
My jaw hit the floor. She handed the cat back. I quietly said, "That is a gift." And Tabitha said, "I know."
