Sucker

When your faithful tabby cat is 18 years old ... and his health problems start piling up ... and you're thinking he won't be around much longer (never mind you've been thinking that for the last 4 years and he's still here) ... well then you just might wind up buying things you used to laugh at in the pet store.  Yes, it appears that I am an idiot.  The cat is laughing at me behind my back, and he's eating better than I am.
