Our wonderful Macy is 12 years old and has been diagnosed with diabetes almost 2 years ago. We discovered it with her weight loss and outside the litter box urnination issues. She's been doing great with a controlled diet and insulin shots twice a day.
About a month ago she started going right next to her litter box, but not all the time. Sometimes its twice a day then nothing for 2 or 3 days. We've made 3 trips to the vet and found nothing. We did decide to up her insulin dose with the vets guidance as her blood sugar was a little high but not horrible. The vet said the elevated levels could be due to us packing to move/stress.
We are at our wits end with this. We clean the 3 litter boxes in the apartment twice a day. We try and watch her constantly and if she heads for that corner we put her in a litter box. We have another vet appointment Tuesday for a final set of tests, but we're afraid that they won't find anything wrong again and it will just be her being stubborn.
