What flea treatment is safe for my pregnant cat with fleas right now?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 11 months and 10 days old | 9 lbs

So Bella is around 5 weeks pregnant and I noticed and took two fleas off of her yesterday. I was wondering if I could used this flea treatment which I had been using but stopped right before she got pregnant. It says it's safe for kittens 8 weeks and older so I'm hoping it's safe for her. I've also seen people say Frontline is good for pregnant cats and it says it has the same "active ingredients as Frontline plus" so can I use it?

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!

    Great question! First I would give Sammy Capstar. It's a one time pill that starts killing fleas in 30 minutes and is safe to give pregnant cats. Then I would follow up with Revolution. This is a spot on treatment that is also safe to use in pregnant cats. You can get both from your vet. Be sure to disinfect the environment. Wash her bedding in hot soapy water, and vacuum all the furniture and carpet surfaces. I hope this helps!
