That's awesome but check again, maybe 2 more times at different times of the day as blood sugar fluctuates every hour I believe, according to one vet here. But my past & current ham (Sylvester) tested normal but on the 2,3 & 4th try he was on the olive green color next to the brown colors on the bottle.
One time he tested brown but that was from contaminated bedding, maybe so I get clean samples now. It's especially nice that he likes to pee in his nesting area. So I remove tissue & clean his tray & in the morning there is 1 or 2 puddles.
Definitely check at least one more time, especially since you have a whole bottle now
lol
Hope you don't need the bottle anymore but it's good to test as they age too.
