We found an old stray back in 1994 who needed medical care and lots of love. We named him Lucky. Our mobile Vet came and examined him, took him to the clinic to get snipped and the whole nine yards. Few months later Lucky was acting strange...like jumping on the bed and stare at us then squat. Crazy but nothing was coming out, that's when it dawned on me that there hasn't been much urine in his box for like a week. The vet said sometimes when male cats are fixed and not on a really good diet (and given his age) they form crystals and can't go and will die from the poison build up if not treated. We had to start feeding Lucky medicated food, with the exception of a few Cheese-Its now and again, he got all better. He was with us for three more wonderful years. He brought us so much happiness. Hope your baby is doing well.
