Today I noticed that Hazel has been producing more urine than normal; I just changed her litterbox yesterday, and it was already mostly soaked with urine by the end of the night tonight. Usually I can go 2-3 days without changing the box. So I changed the box again tonight, and she peed twice in it within 20 minutes. She doesn't appear to be straining, the urine is a normal color and consistency, and she is acting like her normal self. She is eating fine, and her poops are normal. I also haven't noticed any urine outside the litterbox, or dribbling. In fact, she has been racing around the house doing binkies all night. However, I'm still slightly concerned at this sudden increase in urination. I'm going to keep an eye on it for now, and talk to the vet tomorrow, since I have the convenience of being at a veterinary teaching hospital/vet school and can just go talk with the exotics vet whenever  I know that it could be a possible UTI, or also diabetes (maybe a mild case). Any advice, or has anyone had this occur and it be normal? Thanks, as always!

Oh good. So glad the urinalysis came back normal. So maybe having a new crock is allowing her to drink more and once she is used to getting thoroughly "hydrated", she'll slow down a bit. If you notice she seems to continue to consume quite a bit, (more than normal), you might want to have her teeth checked as some bunnies will drink lots of water as a way to soothe tooth issues.
