the good news is that the ingredients listed are not toxic per say. I think they come on . I would be more scared of possibly:
An digestive obstruction (stomach or bowel)from the toilet paper
Pancreatitis from the amount of food she ingested.
A stomach dilatation from the food and the rid-x she ingested.
At this point there is no point to make her vomit if this happened several hours earlier. You may need to wait and see if symptoms .
If i get it right, rid-X is the stuff you put in septic tank?
There are a lot of bacterias. Their website mentioned humans should not be affected by it.
Due to the amount she ate, I wonder if she could get some serious digestive upset.
in would suggest before you get her to the ER.
Stop feeding her for a day
Give her water if no vomiting.
Call the ASPCA center to know if the amount (possibly just give them a possible amount) would be detrimental to her.
They do charge you, but it is worth the call.
