Can a dewormer make my cat act really hyper and restless?

After giving my cat her deworming medication yesterday, she’s been unusually hyper and restless, darting around the house all night. Normally, she's quite calm, so this is out of character for her. Could the dewormer be causing this change in behavior, or is it just a coincidence?

Answer

It sounds like your cat is experiencing increased hyperactivity and restlessness after receiving her deworming medication. While dewormers typically don't cause such reactions, individual pets may respond differently.

  • Monitor your cat for any other unusual symptoms.
  • Consider the various influences on her behavior, aside from medication.
  • Consult a vet if her behavior doesn't normalize or worsens.

In some cases, the stress of medication or the removal of parasites can lead to temporary behavioral changes in cats. It's also possible that other environmental factors may be contributing to her restlessness. If this uneasy behavior persists or you notice additional concerning symptoms, it’s wise to consult with a veterinarian.
