Metaldehyde Poisoning in Cats

Slug and snail baits as well as some solid fuel for camp stoves all contain metaldehyde, which is extremely poisonous to cats, primarily affecting their nervous system. This type of poisoning is often seen in coastal and low-lying areas, where use of slug and snail bait is customary. And even though metaldehyde poisoning can be seen in both dogs and cats, it is more common in dogs.

• Excessive panting
• Excessive drooling (ptyalism)

Diagnosis

You will need to give a thorough history of your cat’s health, including the onset and nature of the symptoms, to your veterinarian. The questions may specifically pertain to exposure to slug and snail baits or other sources of metaldehyde. He or she will then conduct a complete physical examination, as well as a biochemistry profile, urinalysis, and complete blood count (CBC) -- the results of which may be varied. A definitive diagnosis is typically made by verifying the presence of metaldehyde in bodily fluids (e.g., vomitus, stomach contents, and urine).
