Sheba had a blockage once years ago...and the Vet had us use the tubes with the mineral oil/ malt mix. One brand is called PetroMalt...but there are others. Sheba was so sick she was in a semi coma and we could not rouse her.
I'd worry about fiber, should be getting that already in the dry food. All quality dry foods put it in now. Too much fiber + dehydration and impaction occurs.
Doody's cat was stealing dental floss out of the trash and he got an impaction from a ball of it in his bowel! She posted about it about a year ago. Search "Chewie", on the Pet forum.
I hope this is a simple episode for your kitty!
