Record the pattern before the label
Common signs of diabetes in cats include increased thirst, increased urination, weight loss and increased appetite, but one sign cannot confirm diabetes. Dogs and cats can have other causes of increased thirst and urination, so “what happened” is more useful than a guessed label.

Turn “more” into comparable notes
- Water: record times, refills and other sources. In a multi-pet home, write “shared, individual intake unknown” and do not restrict water.
- Urination: record clumps actually seen in a cat tray, observed urination in dogs and any accidents; trips alone do not equal urine amount.
- Record weight, appetite, activity and medication times weekly or as advised. Put food, supplement, hormone or other medication changes on the same timeline.

Contact the clinic first for these changes
Vomiting, collapse, marked weakness, inability to eat or drink, breathing difficulty or rapid worsening should prompt veterinary or emergency contact before the log is complete. The log supports handoff; it is not an assessment.

What to bring and ask
- Bring weight trends, drinking and urination notes, food and medication lists, and recent diet or environment changes. Mark incomplete information as “uncertain.”
- Ask which tests distinguish diabetes from other causes, which trends to monitor, and when to call the same day. Do not ask to copy a treatment because an online label sounded similar.
