advice please, my cats have the F word, only discovered tonight aprox 20 mins ago.
Luckily I had some Stronghold flea stuff from the vets so each of them have been treated ASAP, however, I seem to remember being told that I must worm them aswell.
my question is do I have to wait a few days or can I apply the wormer immediately? I am worried that I will over load their systems especially as one is only a 10 week old baby and/or will make them ill.
please can you advise me
