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.
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.
Yeah it will give her somesort of kidney disease
Yes or no
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.
What on earth does this question even mean
You should report it to a vet immediatly.
Fleas on a cat are probably either dog fleas or cat fleas (these are two different species, but despite the name, either can survive on either a dog or cat ... or for that matter on other mammals). Both of them can and will bite humans.
No. Frontline products should be used on the specified species. This is because one of the main components of Frontline, S-Methoprene is needed in a higher dose in cats. This is because it does not last as long in a cat than in a dog. So, if you used Frontline for dogs on your cat, it may not be as effective. However, this higher dose is still safe to use on a dog - so you could use Frontline for cats on a dog.
at worst case yes. never ever use dog flea repellent on cats
it is considered an overdose and yes it can harm them if you give them to much of the same flea medicine.
