TendTail

If your cat has just been diagnosed with chronic kidney disease, you probably left the vet with a stack of instructions and a knot in your stomach. TendTail keeps it all in one calm, simple place, so you can spot changes early and walk into every check-up ready. Cat kidney disease (CKD, or feline chronic renal failure) is something you manage day by day: the renal diet, the water, the sub-q fluids, the weight, the appetite. Holding all of that in your head is exhausting. This app does the remembering for you. WHAT YOU CAN TRACK • Subcutaneous (sub-q) fluids: amount and time, so you never double up or miss a session • Food and renal diet: what they ate, how much, and whether appetite is slipping • Water intake and hydration • Weight over time, the number that quietly tells the real story • Medications and supplements, with reminders • Symptoms: vomiting, nausea, lethargy, litter-box changes • Vet visits and lab results: creatinine, BUN, SDMA, phosphorus SEE THE TREND, NOT JUST TODAY One off day is noise. A two-week slide in weight or appetite is a signal. TendTail turns your daily notes into simple charts so you can see which way things are heading, and bring real numbers to your vet instead of "I think she's eating a bit less." BE READY FOR THE VET Pull up a clean history of weight, appetite, fluids and lab values in seconds. No scrolling through a notes app, no trying to recall last month from memory.
