Hello, my pet cat was sitting under my bed and I sprayed a bug spray with 0.3% premethrin under it without knowing it was there. Can it be fatal? Should I be worried?

Yes, permethrin toxicity can be fatal in cats if not treated. I am attaching more information from the Pet Poison Helpline below. http://www.petpoisonhelpline.com/poison/pyrethrin/ If you know Chin chim has been sprayed, we normally recommend bathing the cat in Dawn dish liquid to remove the chemical from the fur (before the cat licks it off). Toxicity signs include muscle twitching that can progress to seizures. If you notice any signs of toxicity, please take Chin chim to an emergency veterinarian immediately for treatment. Good luck! I hope that was helpful and that Chin chim is fine. Thanks for using PetCoach.
