Christina knows that her friend has epilepsy. one day while they were at home together eating a snack at the kitchen counter, christina sees her friend start to convulse. christina notes the time and makes sure there aren’t any dangerous objects near her friend. what should christina do next? a) call 911 b)lay her friend on the floor c)hold her friend down d) put something in her friends mouth

Gently lay her down on the floor, I think,  should be the next thing you do.

It would just be adding to the problem if you call the paramedics and she's fallen down and possibly injured herself even more than can be expected from convulsing. Holding someone down while the are experiencing a seizure is a BIG no.  You just have to let them do their thing, and let it pass. And obviously you wouldn't put something in their mouth. You would risk them choking. Hopefully this answer suffices!

no because dogs are cats the product you bought is meant for cats xd
