Another PTr here was raving about salmon oil. You can get a bottle quite inexpensively at a pet store. It's made so that it is not so stinky, but appeals to a cat's nose!
Try and get it in a pump bottle, or buy an empty one to use. Much easier than trying to pour just a little bit.
You might try a small bottle first to see how it works. It's a treat for my cats. I've always given them oil and they have never been constipated - and one is long haired.![]()
