Some cats clearly prefer the juiciest wet foods that include "gravy". And some of those cats only want to lap up the juice! Shelton D. writes:
Shelton, this behavior is more common than you might think. Many cats show a preference for the juicy part of foods with gravy.
Since most pet cats are descended from desert-dwelling wildcats, they have very low thirst drives, so it isn't thirst. It's more likely to be a concentration of the over-the-top flavor enhancers that are added to many cat foods.
Most commercial cat foods, even wet foods, have added flavors to entice cats since their core ingredients are often substandard and would not appeal to cats if offered without enhancement. Cats can become "addicted" to these extra-salient flavors and have their sense of taste dulled by them.
This is why many cats will only eat fish products with extremely fishy flavors. Cats in the wild rarely prey on fish, and pet cats often become allergic to fish proteins, but commercial cat food manufacturers continue to add fish flavors because they're so strong that they overpower the bad or bland tastes of the other ingredients. This can be especially problematic when trying to switch a cat from junk food to more healthy fare.
If you're interested in exploring more healthy foods for your feline friend, there's a great resource over at the Natural Cat Care Blog that lists all of the commercial cat foods they've tested in order of nutritional preference.
Best wishes to you and your gravy-lover!
