What is a vet?

Today I slept in. Dad and mom were tired after a long, hard work week. After a great breakfast I played with my feather, climbed my scratching post, 

and mom opened the shade in the kitchen window so I could watch for squirrels climbing the neighbor’s trees. 

She also made a "vet" (???) appointment for me for Monday afternoon. The broken tooth does not bother me in the least, but mom is careful about health issues and insists that I go in. She talked to Dar this morning and he felt bad that he had not checked my teeth. He spoke to me through the phone and I rubbed against his voice, to tell him that I miss him and love him.
