Questions Owners Ask
Should I go to the emergency vet?
Go now if the cat is trembling after a dog flea product, is drooling, or cannot stand. Permethrin toxicity in cats is an emergency. A brief shiver when a cat wakes up and then walks normally can be watched. Tremors plus hiding and no appetite should be seen the same day.
How much will treatment cost?
Shaking or trembling in a cat needs an exam for pain, a fever, low blood sugar, toxin exposure, and ear disease. Bloodwork is added when the cat is also lethargic or has not eaten. Ask before a full panel if the cause is an obvious painful limb.
Can I treat this at home?
Look for a toxin, a lily, a permethrin dog-flea product, or a fall. Never give ibuprofen, naproxen, or acetaminophen. A cat that is trembling and drooling after a dog flea spot-on needs the clinic now. Permethrin on cats causes tremors and seizures.
