I have a 5-year-old short haired tabby cat, who has been peeing outside his litter box. I am not sure when this started, maybe earlier this year. It would be very random, one day out of the week he would pee either near the front door or near my window door balcony. He eats and poops normally, just would randomly pee outside the box. He has been neutered ever since I got him 5 years ago. He also throws up randomly, one day he threw up 8 times but then went back to acting normal. I am not sure if it was due to him eating too fast and then playing with my other cat. The other cat, which is a long haired cat, has more of an alpha attitude, he always pushes my short haired away from his food and always wins during their play fights. I first thought it might have been territorial so I got two litter boxes, but even then he would still pee near my two doors. Yesterday night, I actually witness him peeing, and I notice he was peeing standing up. Usually when he pees in the litter box he squats and pee. I made an appointment to take him to the VET as this peeing thing has beeing going on for too long. What could be causing this? I am currently a student graduate and do not have a job, so I hope the vet bills won't be too much.
