Can I use Seresto on my pregnant cat? What flea treatments are safe?

To my knowledge, there is only one safe (supposedly) flea / tick treatment for pregnant / lactating cats. That is Frontline. I would still read the label carefully and see if the study they did revealed any weird birth defects in large numbers, but it is definitely supposed to be safe.

It's not specifically labeled as safe for nursing cats, so I would not use it. I recommend using Advantage, which is labeled as safe for use in nursing cats. It cannot be applied to Poofy's kittens, however. If they have fleas, you can safely use Frontline Spray on them. Best of luck, I hope this helps!

The label on Advantage says to consult a veterinarian prior to use in pregnant cats. Typically, this means that insufficient studies have been performed to confirm the safety of this medication in pregnant cats. However, without examining Snot and performing further research, I cannot confirm the safety of this product if she is pregnant. However, Frontline Plus is labeled as being safe for use in pregnant cats. I hope this helps!

If it's not specifically labeled for use in pregnant cats, it's not safe to use on Bella. I recommend using Revolution or Advantage, those are proven to be safe for pregnant cats. I hope this helps!

You can use Frontline plus while they have the Seresto collar but this should not be necessary as Seresto is good for at least 6 months. So I would not recommend applying an additional flea and tick preventive.

I don't think you are going to get a clear answer on this. I've included the company's drug information below. https://merckusa.cvpservice.com/product/basic/view/1047301 Their recommendation is to consult with your veterinarian if your dog is pregnant. I have looked for any information about this product in pregnant dogs and cannot find any which likely means that there hasn't been any testing done. So, the answer is that we likely just don't know if this is safe for pregnant dogs. There are flea and tick products that are listed as safe for pregnant dogs, so I would consult with your veterinarian for a recommendation. Good luck! Thanks for using PetCoach.

Yes you can apply Advantage to your pregnant cat. Giving a bath is very stressful and won’t control the fleas as well as Advantage. Please vacuum the house daily and use a flea treatment on all of the other animals in the household otherwise you may still have a flea problem. If the kittens get fleas I would use a flea comb dipped in soapy dishwasher to remove them from the kittens, and kill them in the bowl of soapy water. Hopefully they will all be gone before the kittens are born. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Baby.
