Why drooling means the clock is ticking
Excessive salivation is often the first visible sign of metaldehyde poisoning, indicating neurological disruption has begun. Your cat's mouth may hang open with thick, ropey drool - a red flag that worse symptoms likely follow. The toxin overstimulates the nervous system, first affecting the salivary glands before progressing to muscle tremors and seizures.
Thirty minutes post-ingestion is prime time for symptoms to escalate rapidly. What begins as drooling can become full-body convulsions within the next 30-60 minutes. These seizures dangerously elevate body temperature, potentially causing permanent brain damage or organ failure without prompt treatment.
What to do while preparing for the vet
Keep movement to a minimum - excitement or stress can accelerate neurological symptoms. Wrap your cat lightly in a towel if they're trembling, but avoid tight restraint. Turn off loud noises and bright lights that might overstimulate them. If possible, have someone else drive so you can monitor your cat's breathing during transport.
Bring any remaining bait or packaging - this helps the vet determine metaldehyde concentration. Note the time of ingestion and symptom onset, as this timeline guides treatment decisions. Don't attempt to give food, water, or home remedies, as these may worsen the situation if swallowing becomes impaired.
What emergency treatment will involve
The veterinary team will act swiftly upon arrival, likely starting IV fluids and anti-seizure medications immediately. Muscle relaxants help control tremors, while cooling measures address rising body temperature. Blood work assesses organ function, and oxygen support may be needed if breathing becomes labored.
Your cat may require hospitalization for 24-48 hours, as metaldehyde's effects come in waves. The vet will monitor for secondary complications like aspiration pneumonia or kidney strain from prolonged muscle activity. Early intervention greatly improves the chances of full recovery.
Why you shouldn't wait for worse symptoms
Some owners hesitate, thinking 'it's just drooling' or 'maybe the worst has passed.' With metaldehyde, the opposite is true - early signs mean the toxin is actively affecting the nervous system. Waiting for seizures to start before seeking help drastically reduces treatment success rates.
The drooling phase offers a critical window where medical intervention can prevent the most dangerous symptoms. Once full convulsions begin, controlling them becomes harder and recovery takes longer. Your quick action now could save your cat from irreversible damage.
