My experience with problematic crystals, leading to blockage etc. has been in 1971, and recently. jeez I'm old.
Anyway both cats were/are orange/buff male domestic short hair.
I am wondering if this is just a coincidence, or if these cats are genetically predisposed to this condition. What type of cat is your FUS cat?
