i know you mean well, and honestly i do think any owner that lets their pet(s) socialize and can afford flea treatment(s) should administer it, so i'm not trying to scold you or anything, but some cats can have adverse/allergic reactions to advantage flea stuff, either on their skin or by ingesting it, so i'd personally recommend that you tell them you've done it. worst case scenario, they'll be mad at you, but better safe than sorry on behalf of the animals imo.My neighbours always keep their 2 cats outside and they are covered in fleas so I put some Advantage flea repellent on them. I didn't even ask my neighbour's permission I just did it lmao. It was 80 bucks for 4 doses (my 2 cats + 2 neighbour cats) so they are secretly welcome.
I thought the same thing but the one cat is really covered in flea sores so I decided to take the risk. I got this stuff from the vet and not the pet store where they sell low grade stuff that are more likely to cause reactions. I've seen both the cats and they're doing good luckily. Hopefully their skin can heal for a bit now.i know you mean well, and honestly i do think any owner that lets their pet(s) socialize and can afford flea treatment(s) should administer it, so i'm not trying to scold you or anything, but some cats can have adverse/allergic reactions to advantage flea stuff, either on their skin or by ingesting it, so i'd personally recommend that you tell them you've done it. worst case scenario, they'll be mad at you, but better safe than sorry on behalf of the animals imo.
