ALL cats need to be spayed or neutered. When he is neutered and his hormones settle down, he will almost certainly stop spraying and the strong smell will lessen.He just sprayed now. He meowed me to open the crate and I watched him carefully. He smelled the house for half an hour and sprayed on the wall. I'll collect fecal sample and take him for blood test. But how should I collect urine sample if he's spraying. His body temperature is 100.2 F now.
ANY trouble in urinating can be LIFE-THREATENING. It is a serious emergency. He needs help right away.
