You should report it to a vet immediatly.
No, a flea is a flea. There is no "cat flea" or "dog flea". Its just a flea and its just as likely to get a cat or dog.
Yes! It well harm your cat because dog flea drops are much too strong for a cat! If you do then immediately wash it off with a wet whipe or a wet (paper) towel! You should just give it cat flea medicine. that is most safe.
There likely will be no problem if the amount of canine flea medicine ingested was within the dosage range for a dog similar in size to the cat, but take the cat to a veterinarian if it swallowed a much larger amount of the medicine or if it appears to be sick. Bring the container of medicine along with its instructions with you if you do go to a veterinarian.
bring your dog to the vets ASAP!
Yes or no
it is considered an overdose and yes it can harm them if you give them to much of the same flea medicine.
Dog fleas are a different species than cat fleas, and flea collars are designed for the specific flea type. A dog collar on a cat would probably be less effective, or may not work at all.
flea is just like pronouncing flea on a dog or cat, pretty simple
The flea jumped on the dog and the dog ran away crashing into a pole thus he fainted.
You are not supposted to put flea/ tick medicine on a puppy. If the dog is usually under 6 months to a years of age it should not be put on. It can cause the dog to get sick. If you have a small dog but is older it should not get sick and it shouldn't shake unless it has some alergic reaction to the medicine. I have a small dog and we use flea medicine on him and he is fine and never has fleas.
yes it does
Very possible that it WOULD be harmful. Different compound for different skin, in a different concentration. Please don't try it.
