here goes, for the past two days Jack's pee has a foul odor to do. Yes I know urine doesn't smell like roses, but this is a new smell, almost oniony? Also while scratching his belly I noticed a small lump inside his penis. He does go to the bathroom frequently but I do leave him out water for his leisure. I am very worried, have a vet appointment in 2 weeks, wondering if I should have him seen sooner or if his mommy is just being a worry wart.
