The quiet signs it's time for a house call
Cats hide illness professionally and dogs forgive too much — the behavior changes that should trigger a strip before a symptom.
Cats are prey animals wearing predator costumes, and hiding weakness is written into the species. By the time a cat looks sick, it has usually been unwell for weeks. This is why urinary disease — the most common serious illness pathway in indoor cats — is caught late so often, and why the litter box is genuinely the best diagnostic window in the house.
The box signs worth a strip: visits that get more frequent but produce less, longer digging and straining, crying in the box, going outside the box in a previously reliable cat, and any urine you'd describe as pink-tinged or unusually dark. Off the box: drinking noticeably more water, sudden weight loss with a fine appetite, and coat neglect in a former perfectionist.
Dogs broadcast on a different frequency: asking out more often, stopping to squat repeatedly on walks with little result, accidents from a house-trained adult, licking after urination, and the water bowl emptying faster than usual. Senior dogs and unspayed females carry the most urinary risk; diabetic breeds add the thirst-and-hunger pattern.
Our protocol for any of these: collect and run a strip within a day — sand for the cat, pole for the dog — write the result down, and retest in forty-eight hours. Two clean strips and a normal-acting pet buy you watchful waiting. Anything else goes to the clinic with your readings, where a vet starts from your data instead of from zero. Early is cheap; late is not — in every sense.
