His bloodwork 4 months ago was fine aside from kidneys issues (stage 2 kidney disease). The results today said his kidneys were fine, back to normal (?) the vet has no idea how that happened. Unfortunately the diabetes is back she said his glucose level (I think) was in the 30's but shouldn't be higher than 9.7.
We only did insulin for 2 weeks last time so we have never done home monitoring.
