My cat accidentally got dog Frontline on her. Will she be alright?

Pet's info: Cat | Mixed Breed | Female | spayed | 9 years and 11 months old | 5 lbs

Hello. While apply frontline plus to all animals I applied to my two dogs first, than my cat hers. While applying she got so angry with me, I had to drop the little vile so I could hold her in place. I accidentally picked up the open vile I had applied to my dog. I believe 1 drop left at the bottom of the dogs vile got onto my cat. Is she going to be okay? I tried to bathe her but she scratched me up pretty bad. She isn’t acting strange and in all honesty we do not have funds to run her

One drop from the dog's vial of Frontline shouldn't be a problem. The concentration is often the same, just the volume applied is more for a dog. Keep an eye on her just to be safe but she's probably fine. If she does show any signs of sickness, refusal to eat or drink, lethargy, drooling, vomiting, etc., get her in to your vet or an emergency clinic right away.
