Hello Community

I am a first time reptile owner with a ball python that just short of 24". The temperature is constant, and the humidity is kept constantly between 50%-65%, and it has a couple hiding spots and a water bowl. I've had it for about seven months. It has shed probably two or three times since I've had it. I feed my ball python once a week on hoppers. Its defecation schedule was pretty routine (every three or four feedings), with the urates here and there between. Usually when it pooped, its tail end would get a little bigger, and there would be a poop in the cage a couple days later. After its last shed however (early December), the..."lump" (for lack of a better term) is taking longer to appear, and it has not urinated for a while. I'm starting to get concerned, and I admit I'm a little neurotic when it comes to a new pet, but I wanted to verify the validity of my concerns.

I appreciate your guidance. =]
