What happens if my cat gets an accidental flea medicine overdose?

Cats are exquisitely sensitive to flea treatments, so there is a potential this could cause problems in Monty. I would wash him off thoroughly with warm water and Dawn dish soap. Watch him for signs of toxicity which include excessive salivation, paw flicking, ear twitching, vomiting, diarrhea, depression, incoordination, and muscle tremors. If you see any of those, rush Monty into a vet immediately.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Dory. Oh no! I'd give her a bath to get it all off, and just watch her. If you see muscle tremors, excessive salivation, paw flicking, vomiting, diarrhea, or lethargy, take her into a vet immediately. Hopefully, she will be fine.

The problem is usually the reverse, using dog flea treatment on cats. Cats are more sensitive to some ingredients than dogs. Your dog should be fine, especially if it is one of the products that is used on both species, just the dosage is different. If it is a product meant for cats exclusively, I suggest calling a pet poison helpline, such as this one: http://www.petpoisonhelpline.com/contact/

You were very smart to wash the medication off Cookie. If you did not use dish soap, I would recommend to rewash the area using dish soap as it is very good at stripping the coat. While I cannot be 100% positive that everything is ok (as I cannot physically examine her), it's generally a good sign that she has calmed down and is acting more normal. You have two options, take her into the veterinarian or monitor her. If you want to be as safe as possible, you could get her into the veterinarian tonight for an examine as they would be the best ones to determine if there are any neurologic abnormalities or any other causes of concern. If you choose to monitor her, you need to watch her closely for increased respirations, open mouth breathing (panting like a dog would), stupor, dizziness, trouble walking, seizures, hyper salivating or other abnormalities that involve her central nervous system. If Cookie displays any of the above abnormalities, I would recommend to take her straight away to the veterinarian. Make sure that she is eating and drinking. When in doubt, take her in as its better to be safe than sorry. Go with your gut. I would not recommend to use this product again on her to be safe. Although reactions can occur with any product, I think Revolution is generally well tolerated and I routinely recommend it. You may also talk to your regular veterinarian about appropriate products to use in your area if you have specific risks like ticks. I noticed that you listed her weight as 4lbs (which would be very small for an 8month old cat) and the product is labeled for 5lbs. While it may be a typo, make sure to always use the appropriately sized product to decrease the potential for side effects. I hope this helps and that Cookie recovers normally! Thank you for using Petco Pet Education Center, formerly Petcoach.

Thanks for using Petco Pet Education Center, formerly Petcoach! I definitely understand how you feel and I am so sorry for your loss. It is very unlikely that this happened from applying too much flea medicine. This is more likely due to the other symptoms you mentioned including the diarrhea, difficulty urinating and fatigue. This could have been due to a disease that had not been identified. Again I am so sorry for your loss and I will keep you in my thoughts as you go through this difficult time.

Oh that's not good! If it's a topical medication, wash it off now and monitor your kitten for signs of toxicity. Signs include tremors, excessive drooling, ear twitching, vomiting, or diarrhea, take her into a vet immediately. Best of luck.

This is an overdose, and you may see signs such as vomiting, diarrhea, nausea, and anorexia. Studies show no permanent damage to cats given an overdose, so that's good news. If you do see any of those signs I mentioned above, have B seen by a vet to be safe. I hope this helps!
