My vet gave my cat a Convenia injection for an infection, but now she seems more lethargic and isn't eating much. Is this normal, or should I be worried?

Last afternoon, my vet administered a Convenia injection to my cat to help with her infection. Since then, she's been quite lethargic and hasn't been eating as much as usual. Is this a normal reaction to the medication, or should I be concerned about her well-being?

Answer

It's understandable to feel concerned when your cat displays unusual behavior following a treatment. Lethargy and a decreased appetite are commonly reported side effects after receiving a Convenia injection.

  • Post-injection lethargy can occur in some cats
  • A reduced appetite is a noted side effect of Convenia
  • Monitor your cat closely, especially if symptoms persist

Convenia is a long-acting antibiotic used to treat bacterial infections in pets. While it is generally well-tolerated, some cats may experience temporary lethargy and a decrease in appetite after receiving the injection. These side effects are usually mild and resolve on their own. However, keeping an eye on your cat's condition over the next couple of days is important. If her lethargy persists or worsens, or if she refuses food for an extended period, it would be best to consult with a veterinarian for further advice.
