I completely understand why you're worried. Missing a dose of heartworm medication for your girlfriend's cat is not uncommon, and the good news is, there’s usually a straightforward way to handle it.
Heartworm prevention medication is most effective when given consistently, as it prevents larvae from developing into adult heartworms. Missing a single dose might slightly increase the risk, but cats are relatively resistant to heartworms compared to dogs. However, we still want to maintain a regular prevention schedule.
Here’s what you can do: Give the missed dose as soon as you remember, unless it's been 30 days or more since the last dose. In that case, consult with a vet to determine the best course of action. Moving forward, set reminders to help stay on track, ensuring your cat is covered year-round.
Watch for any signs of potential heartworm infection such as coughing, lethargy, or difficulty breathing. These symptoms can be subtle but are important to catch early.
For peace of mind and tailored advice, I recommend scheduling a video consult with one of our vets via Dial A Vet. We can provide guidance on the next steps and help keep your cat healthy and happy.
