Is it normal for a cat to be lethargic after getting a Convenia injection?

My cat received a Convenia injection yesterday at the vet's office, and today she seems unusually lethargic, spending most of the day sleeping and not showing much interest in her usual activities. I’m worried that this isn’t normal since she's usually very energetic. Is it common for cats to feel this way after such a treatment, or should I bring her back to the vet?

Answer

It's understandable to be concerned when your usually energetic cat becomes lethargic after receiving a Convenia injection. While some changes in behavior are normal, monitoring for any concerning symptoms is key.

  • Mild lethargy can be a side effect of Convenia.
  • Stay alert for any additional symptoms or changes in behavior.
  • Contact your vet if you notice symptoms worsening or new signs appearing.

Convenia is a long-acting antibiotic commonly used in cats. It's generally well-tolerated, but some cats may experience mild and temporary lethargy as they adjust. This typically resolves within a day or two. It's important to ensure your cat is eating, drinking, and using the litter box as usual. If your cat seems unusually unwell, or if the lethargy persists or worsens, you should consult your veterinarian to ensure everything is okay.
