Whats wrong with my cat?

Is the cat using the litter box okay? Or is he urinating in strange places? He could have a UTI (urinary tract infection). What kind of food are you giving him, is it only dry food? Is he provided with plenty of water? If he doesn't have a UTI, he could be reacting to a change in his life. Is there a new cat in the house? Are you away from home more? It might be as simple as giving him a bit more attention. You don't want to stop him from cleaning himself, but I know it is a concern. I lean towards a UTI, because Willy was over cleaning himself, and there was blood in his urine. Another possibility is have you changed his diet? He could have a food allergy, sometimes a new food is too "hot" for them. Not hot in the spice sense, but the ingredients are too strong for his system. Did you change detergent for your laundry? It sounds strange, but if the cat sleeps on the bed or is in contact with your clothing the detergent residue could be irritating him. I will check my cat books and see what they have to say, but I am fairly sure that they state that it is because of a UTI. One more question, is it hot where you are right now? I have had cats that will pull or lick the hair away from their private areas so that they are a bit cooler. It is a trial and error type process of elimination. If the cat is eating okay and drinking plenty of water, then check for allergies...think about if something you normally use has changed, if his life style has changed, etc.
