You can also add some fiber to her canned food. Some people like to add a bit of canned pumpkin (some cats even like it just plain!). My cat doesn't, so I just add a bit of ordinary psyllium fiber (human style, from the drugstore) to the 1/4 can of wet food that also contains his skin/coat and joint/urinary supplements and his antihistamine (and plenty of extra water - it's really more "gravy" than food!) Psyllium is flavorless and proven safe in cats. I just snip the capsule open with the scissors and sprinkle it right in.

The problem with petroleum is that it can coat the intestine and keep a cat from absorbing nutrients. If only they made psyllium Temptations!
