Who are you?

I liked this quote in the window of our local chiropractor window.

Our cat Taz had his annual check up and vaccination. The new vet  who saw him  noted from his records that he " had form". 

True to " form" he growled and hissed at her when she approached with a needle.

She said he was in good health- for a 16 year old ( approximate) cat.
She did not check his teeth nor his claws which needed cutting.
