Are ADHD medicines toxic to cats?
Severe
No — ADHD medicines such as methylphenidate (Addwize) are stimulants that over-excite a cat's brain and heart. Signs come on fast: agitation, wide pupils, a racing heart, tremors, overheating and seizures. Go to a vet now with the pack.
Why severe: Even small ingestions can cause life-threatening tremors and seizures (Pet Poison Helpline).
