Pregnant cat and anti flea treatment

2 weeks ago I noticed some flea on my 8 months old female cat so I used Sergeant Silver anti flea and tick spray + spot on anti flea. Today I noticed she has enlarged pink nipples + slightly enlarged abdomen so she might be 3 weeks pregnant. Are the babies and the mommy to be in danger? what are the effects on the unborn kittens? Please help

I tried to Google the product to see what the warnings were. I am not good at this.  Do you still have the bottle?  What does it say?

I know this is not a product I've seen mentioned as safe for pregnant cats and kittens on this site.  That doesn't necessarily mean it isn't.   I did notice that it lasts for 14 days and not a month so maybe it is not that bad.

You can contact your vet over the phone and ask what he thinks.  Otherwise I guess it just wait and see.

Sorry I wasn't any help.  Someone else may come along with more experience int this area.  Like @catwoman707 or @stefanz

That early, it hopefully isnt  dangerous for the unborn.  And hopefully not for mom either..   Essentially I agree with Handsome Kitty.

Advantage II is known to be safe on pregs (and others).   Revolution should be OK too - esp if you manage to find the version for high pregs and moms.
