I took him to the vet and she gave him an exam. Said she didn’t feel any tenderness or abnormalities on him She told me that it could’ve been a behavioral issue, either because his litterbox was too clean, or if his veggies had extra water on them that day which led him to pee more. She gave me the option of observing him for a few days or going ahead with a urinalysis. I wanted him to have the urinalysis, even though i was beginning to suspect he was ok. She kept him for the day so she could collect some pee. She apparently couldn’t collect it, because he peed on the carpet when she let him free to play. I went to pick him up, and she gave me a syringe to collect the pee when i got home if i could.
But when i got him home, I noticed that he was totally acting normal again, even acting happier than befor so I just decided to leave him alone. I’m pretty sure he was just being a brat that day now.
