I have read on here that a cat with a uti might have crystals in their urine. I always keep an eye on my kitty, not obsessively but just to make sure he is okay and everything is working properly. I was just wondering, I had a look in the box after my little boy kitty went for a wee and I looked at his wee in box and I don'tthink I would be able to tell if he had crystals in it? What do they look like? I know this sounds silly but I am imagining little glints of light like little diamonds in it? If not, then how would you know? I am only asking so that I can be aware but I have been unable to find answer. As my cat is being really fussy with his expensive high grade wet food, my bf has got him some dry food which I am not keen on. I know that dry food has been linked to uti's and would just like to know what to look for. (he won't be on dry for long tho). Thanks for any info.
