Constipated 6lb male cat, feces are at end of rectum and protrude ever so slightly, what to use for a laxative?

Cat Question: I have an otherwise healthy, but constipated,6lb male cat. Never has been before. Strictly inside cat, accustomed to drinking water from a fountain, which we disassembled in prep. to move. Between the stress of the commotion and having to drink from a bowl (which he hates) he has dehydrated (I assume)and now is straining to defecate. Feces are at end of rectum and protrude ever so slightly, but withdraw.
I have cod liver oil, olive oil and canola to use for a laxative, but not sure of dose and have already called vet to make sure if no results I can bring in am.
Dosage?

Hi Juan,

Just mix a little olive oil in with the food, or give canned fish in oil which works well.

There is also a product called laxatone which you could find at a pet store (or any hairball remedy will add lubrication to the gut.

Keep the cat well hydrated and call your vet if no progress.
