How can I get my 14 year old cat to transition from only dry food to wet?

After a couple of bouts with constipation, my vet suggested that I introduce wet food into my cats diet. She has only been eating dry for 14 years, never was interested in the wet food, although we did try. It has been a very difficult thing to do, we have gone through several cans of wet food. Some of them she won't touch at all, and some she eats, we think she likes it, buy some cans of it, all of a sudden she won't touch it anymore! She has to take lactulose syrup and we have been giving her joint medicine, which is hard to do if they won't eat the wet food. I really dislike giving it to her in a syringe, and so does she! One thing she really likes is regular tuna (our kind), she will eat that, but even then, she mostly licks the juice. Also, I know that isn't a thing to give to your cat full time. I am at my wits end with this, we aren't sure what to do next. I welome any suggestions! Thanks in advance. Sheila Valenti, "Princess Jasmine's" attendant. :)
