Glow sticks

Caution

Verdict

Caution — the glowing liquid is usually dibutyl phthalate, a terrible-tasting irritant.

Toxic principle: dibutyl phthalate (usually a taste irritant, not a high-dose systemic toxin)

Verdict

Cats bite glow necklaces at parties. The liquid makes them drool, foam, and look miserable. Most cases are taste-irritant only, not a high-dose systemic poisoning — but the cat can still inhale foam or get liquid in the eyes.

Symptoms to watch for

  • drooling
  • foaming
  • pawing at the mouth

What to do

Wipe the mouth and fur with a damp cloth. Offer water or a bit of wet food once they stop foaming. Call a vet if drooling lasts, eyes are involved, or the cat is lethargic.
