I have a male cat who is eight months old. I recently caught him peeing on my couch. This lead me to watch him like a hawk and I've noticed after he urinates he has tiny white crystals . Been googling and wondering if they are Struvite crystals? My googling is leading me to believe the condition is stress related and there is not a medication but diet needs to change? If any one is familiar with this condition I would really appreciate some insite.
