Hi, my cat is pregnant and has fleas. Can I use flea treatment on her right now?

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.

Frontline is safe to use on pregnant cats. You will need to vacuum everywhere she has been, disposing of the bag outdoors immediately after. Wash all bedding as well. You should also use an area treatment to prevent reinfestation. Use a topical preventative monthly for at least three consecutive months, preferably year round.
