Hi Kari,
Late getting to Mocha's condo today, but wanted to pop in. The bounces are frustrating. It's easy for me to say this now, but try to not let Mocha's numbers dictate how you feel. That emotional rollercoaster is no fun.
With her pee incidents, is there any possibility that Mocha's got an infection? I apologize if this has been asked and addressed before. How about her teeth? We're pretty sure my guy Eddie fell out of remission either due to a low grade UTI or a dental infection. Eddie underwent a dental last February and had at least four (I forgot how many now) extractions. I'm pretty positive he needs more dental work, too. Bad mouths and FD seem to go hand in hand.
You've probably read that bounces can be caused not only by low numbers, but also by steep drops. I suspect that may be why you're seeing the blacks. A drop from the 500's into the 200's is a pretty big drop ,which can set off the next bounce. I do wonder though, if Mocha might be sneaking some lower numbers (blues?) in earlier in the cycle. She's shown the ability to clear from the 400's down to the low 100's in a single cycle. Even on "pokie break" cycles, it might be interesting to see a +2, to see if she's coming down - and if so, grabbing one or two more tests to see how low she's actually getting.
Mocha, time to put the trampoline away.
