Antifreeze poisoning
Quick answer
**Antifreeze is a winter emergency.** Ethylene glycol causes fatal kidney failure in cats and dogs. If you suspect any ingestion — even a lick — phone your vet or **Animal PoisonLine on 01202 509000** immediately. Never use antifreeze where pets can access it; clean spills at once.
Key takeaways
- Ethylene glycol in antifreeze causes fatal kidney failure in cats and dogs — even a small lick can be enough.
- UK winters see more cases when drivers drain and refill coolant; spills on driveways and garages are a common exposure.
- Call your vet or Animal PoisonLine (01202 509000) immediately — do not wait for symptoms; the treatment window is narrow.
