By the time symptoms are obvious, 75% of kidney function is gone. Annual bloodwork after age 7 is the difference.

The cruel timeline
Feline kidneys can lose 2/3 of function before any visible signs. By the time your cat is drinking and peeing more, the disease is moderately advanced.
Early detection tools
- SDMA — newer marker, catches kidney decline 1-2 years earlier than creatinine
- Urine specific gravity — early sign of concentrating ability loss
- Annual senior bloodwork after age 7
What changes if caught early
- Diet shift to renal support food
- Hydration increase (wet food, fountains)
- Manage hypertension, electrolytes
- Slow progression — many cats live 3-6+ years post early diagnosis
Late-stage signs
Weight loss, poor coat, vomiting, mouth ulcers, weakness. Treatment becomes about quality of life rather than slowing the disease.
What you can do today
- Annual bloodwork at every cat visit after 7
- Encourage water intake (fountains, multiple bowls, wet food)
- Avoid nephrotoxic medications without vet guidance
