Hello there! It sounds like you’re doing a great job being proactive about your kitty’s health. Dealing with worms can indeed be frustrating, but you're not alone in this!
Roundworms and tapeworms are common in cats, especially those who are newly adopted, as they can easily pick up these parasites from their environment. It's possible that your cat is still passing worms as part of the deworming process, or it could be a case of new exposure or an incomplete initial treatment.
Nexgard Combo is generally very effective, but sometimes it requires a follow-up dose to fully eliminate all parasites, especially since eggs can hatch after the first treatment. Giving another dose sooner than recommended isn't advisable without veterinary guidance to avoid overdosing or potential side effects.
At home, ensuring your cat's environment is clean can help. Regularly wash bedding, vacuum carpets, and keep the litter box clean to prevent reinfection. Maintain good hand hygiene after handling your feline friend and their belongings.
Watch for signs such as continuous vomiting, diarrhea, persistent weight loss, or a bloated abdomen. These may indicate a more serious issue that needs immediate attention.
For personalized advice, consider booking a video consultation with one of our vets at Dial A Vet. They can provide specific guidance tailored to your cat's situation and help you address any concerns.
Adopted cat had worms (roundworms, tapeworms), was treated with Nexgard Combo; 17 days later has roundworms, vet gave us another dose of Nexgard Combo to give him in 2 weeks. Is there any dewormer we can give him sooner than that?
I’m reaching out because I'm feeling pretty stressed with my new fur baby’s situation. We adopted this sweet boy about a month ago, and soon after, we discovered he had a worm problem—both roundworms and tapeworms. The vet initially treated him with Nexgard Combo, which I hoped would do the trick. But here we are, 17 days later, and he still has those cursed roundworms. Our vet advised us to wait another two weeks before giving another dose of Nexgard Combo, but seeing him still struggling with those creepy crawlies is breaking my heart. I can’t stand the thought of waiting that long while he’s clearly uncomfortable. Is there any safe dewormer or treatment option we might consider giving him sooner? Any advice on what I can do to help him feel better in the meantime would be so appreciated. My little guy deserves to be healthy and happy, and I’m really anxious to get him there. Thanks, everyone!
