My 2 year old male cat has been urinating about every 2-5 minutes for the past 3 days...he has also been spending more than a normal amount of time grooming his genitles. I don't know what's wrong. He seems fine other than his frequent visits to the litter box. He has had a normal supply of water and has had his usual appetite. Nothing seems to have changed in his behavior at all except for that. Can anyone tell me what's wrong? I would like to know if there is anything that I can try before I spend hundreds of dollars for a vet bill. I love my cat but I'm a college student, on a college student's budget...so I would like to try any available alternative methods of treatment.
