Spot ons & cats grooming each other

Kim_kim

I have two cats.  I use spot ons for fleas & worms.  They groom each other all the time.  I do worry about them grooming after I’ve applied spot ons.  I can’t stop them.  Anyone else worried about this?

I really wouldn't worry about this. They are often tested at far higher concentrations for things like oral ingestion and are still safe. 
Read the leaflets that came with the products, that should reassure you.

I usually try to pick a time of day where they are settling down for naps so they're less likely to be grooming each other and keep them separate for a bit if I can as well.
