Hello, Susan and welcome.
I'm so sorry Honey is having this problem.
Foul smelling poop that has blood on it is usually attributed to intestinal parasites; not so much worms, but single-celled organisms that cause two conditions: coccidia and giardia. Here is more information:
Ask your vet to do a fecal sample analysis if this was not already performed. Sometimes, it takes several times to test the fecal, before signs of these parasites and their eggs, show up. These conditions can be treated with specific medications.
If it hurts her to defecate, and none of the medications the vet recommended have helped, try to encourage her to drink more, feed only high quality canned food, as it contains more moisture and you can even add some water to it. If lactulose wasn't yet tried, discuss this with your vet. Here is more information on how best to feed our cats, in a series of articles written by a feline veterinarian: http://catinfo.org/
At this age, it's possible that Honey has developed megacolon and in addition to increased fluids, she will also benefit from increased fiber in her diet. You can mix 1 TBS of plain, canned pumpkin (not pie filling) into a small amount of her canned food, twice a day (followed by her regular meal) and see if the beneficial natural fiber is helpful. Here is more information about this condition:
I hope things will improve for Honey and bless you for taking such good care of her!
