Avocado Ingestion Dangerous to Cats

My blue Abyssinian girl "Lilo" loves avocado. It is second only to cantaloupe as her favorite treat. Not only does she eat avocado with no adverse affects, it actually helps her health. She has a rare form of FLUTD, in that she forms ammonium biurate crystals in her urine. It is suspected that she has a portosystemic shunt in her liver which is responsible for the buildup of ammonia and uric acid in her bloodstream, the two compounds which form the crystals in her urine. Acidic urine is a hospitable environment for these crystals but they dissolve in alkaline urine. Prescription alkalizing agents are given to her but they do not work as well as fruit which is known to alkalize the urine. Is it a coincidence that she loves and demands these foods which help relieve her condition? I've often wondered if the body knows what it needs to function better and those needs are expressed as food cravings, even in our pets.
I've veered a little from the topic but in summary, my cat doesn't seem to show any bad reaction to avocado. My vet is aware that I feed it to her and had no objection.

I live on a small farm with lots of feral cats around we feed them some dry cat food but they also seem to like the avocados that fall from the tree we have. I have never seen one cat get sick and they all seem healthy.
