Should I separate cats after flea treatment if they lick each other?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 4 lbs

Hello , I have a rescued female cat which gave birth to a litter of 3 ( now almost 11 weeks old) and all 4 of them have quite a few fleas on them. I was considering treating them with spot on treatment (all 4) they occasionally lick and clean each other so I was wondering if they need to be isolated for some time during the treatment. Please advice

You can use Frontline spray on all cats, which should not be detrimental in case they groom each other. Unfortunately fleas hop on to drink and then hop off again and live in the environment. So you need to put flea powder in your vacuum cleaner and regularly vacuum your house that kill all fleas, eggs and larvae.
