20100901 cats are carnivores
Cats are bad for wild birds; they kill as many as 100s of millions of birds each year. The average cost for a cat is $1035, $115 of that is food. - 

This final note: Today is National Cat Day.

To mark the occasion, the private car service Uber has been doing something special.

For $20, they'll bring you a cat. And cupcakes.

A total of 15 minutes of kitten time.

Proceeds to your local cat shelter.
