Start here: Whiskers' labs strongly suggest an overactive thyroid (very common in cats over 10) along with an early kidney signal that's currently hidden by the fast metabolism. The top three things to bring up with the vet: a thyroid treatment plan, a follow-up panel after thyroid is controlled to see the true kidney picture, and rechecking liver values after treatment. Treatment options are well-established and most cats do very well.
Whiskers has lost almost two pounds over the past year despite eating like she's starving — sometimes meowing at her food bowl an hour after a meal. Her family has noticed she's drinking far more water than usual, and her once-thick coat has thinned. Her vet ran a senior cat panel. The story lines up clearly: this looks like a common hormone problem in older cats, and there's a kidney signal underneath that's also worth attention. Both are manageable.
Range: 0.8-4.7 ug/dL
Total T4 (thyroid hormone) is well above normal. Combined with Whiskers' signs — eating more than usual, drinking and peeing more, weight loss, hair coat changes — this result strongly supports a diagnosis of an overactive thyroid (hyperthyroidism), which is the most common hormone problem in cats over 10.
Several treatment options work well for this — your vet will walk through them. The main ones to ask about: a daily medicine called methimazole (often the starting point), a one-time radioactive iodine treatment (often curative), or a special iodine-restricted diet (slower-acting). Most owners try methimazole first to see how Whiskers responds.
Range: 0.8-2.7 ng/dL
Free T4 confirms the thyroid hormone elevation seen above — this is a strong, consistent signal, not a one-off reading.
No extra thyroid testing is needed before starting treatment — talk with your vet about which option fits your situation.
Range: 0-18 ug/dL
An early kidney marker (SDMA) is an early kidney marker, just above the normal cutoff. In cats with an overactive thyroid, the fast metabolism can make the kidneys look better than they actually are — so this small An early kidney marker (SDMA) bump may be flagging early kidney changes that are currently 'hidden.'
Plan to recheck An early kidney marker (SDMA) and creatinine about four weeks after the thyroid is well-controlled — that's when you'll see the true kidney picture. This is standard practice for hyperthyroid cats.
Range: 0.8-2.4 mg/dL
Creatinine is in the middle of normal range — but interpret with care here. An overactive thyroid speeds up blood flow through the kidneys, which can artificially lower creatinine. Worth watching this number after thyroid treatment.
Tracking after thyroid treatment is the key step.
Range: >1.035 (concentrated)
Urine concentration test (USG) (urine specific gravity) shows how concentrated the urine is. Cats are usually very good at making concentrated urine, so a lower number is worth noting. Combined with the An early kidney marker (SDMA) result, this adds to the early kidney picture.
Repeat urinalysis in 4-6 weeks. If urine stays dilute and creatinine starts climbing once thyroid is treated, your vet will likely transition Whiskers to a kidney-friendly diet.
Range: 30-100 U/L
ALT is a liver enzyme — when it's high, it can suggest liver stress. A mild elevation is very common in cats with an overactive thyroid, and it almost always normalizes after thyroid treatment.
Recheck in about 4-6 weeks after starting thyroid medicine. If it stays high, your vet will look deeper into liver health.
Range: 20-90 U/L
Alkaline phosphatase is just above normal — also commonly seen with an overactive thyroid. Not concerning on its own.
Track at the follow-up visit.
Range: 30-45%
A high red blood cell count is common in cats with an overactive thyroid (thyroid hormone nudges red-cell production up). This usually normalizes with treatment.
Recheck the CBC at 4-6 weeks.
Range: 3.5-5.5 mg/dL
Phosphorus is at the top of normal. Worth tracking as the kidney picture becomes clearer after thyroid treatment.
Monitor on the follow-up panel.
Range: 3.5-5.5 mmol/L
Potassium is at the bottom of normal. Cats with overactive thyroid and early kidney changes can sometimes drift into low potassium. If it drops below normal at follow-up, your vet can easily add an oral potassium supplement.
Track at follow-up; your vet will guide if a supplement is needed.
