My cat is an active outdoor cat, but has always tended to be a little chubby. This past winter being colder than usual, she was a lot less active and really put on weight over the winter. We are using portion control to try to keep her caloric intake at the correct level (following instructions on the packaging) but she always whines for more (and what can I say - my kids are suckers for that little furball's mewling).

As a result we are trying out Healthy Weight Chow to see if this will make a difference. Now that the weather has warmed and she's outside again full-time, she is slimming down some though it's hard to say if this is due to more running around versus the different diet. She certainly whines less for food when her bowl is empty, but again - this could be due to hunting too. We have found a few half-eaten mouse corpses around the yard.

Either way, I have always fed my pets Purina products and feel pretty good about doing so. I will certainly continue doing so for the time being. Both my cat and dog's coats are full and shiny, and (sorry for the TMI) their BMs are healthy too.
