When can I apply Advantage flea drops after my cat's vaccine?

Updated On September 23rd, 2025

Pet's info: Cat | Turkish Angora | Male | unneutered | 4 lbs

My cat is approximately 8 months old and we've recently vaccinated him with Felocell-4. I saw him itch so I want to use Advantage drops against fleas. It's sprayed on the same place where the vaccine is done, right? How much time should it pass after the vaccination so that I could do this?

Advantage drops should be placed on the skin on the back of the neck, where the cat can't reach to lick them off. It's fine to apply the Advantage immediately after giving the vaccine if needed - no need to wait.
