Fenbendazole for cats - goat formulation?

My vet wants to try fenbendazole for my little rescue cat who has been suffering from watery diarrhea for about 8 weeks now. Vet is out of town, did not give me a prescription, and I cannot reach her to confirm if the 10% 100mg/ml suspension I received from Amazon, which turns out to be for goats, is appropriate.

For the sake of my little kitty, my mental health, and my carpet, I’d like to start ASAP–does anyone know if this formulation is cat-safe?

(For anyone who’s curious, fecal was negative for everything except c. perfringens alpha toxin, which has been non-responsive to 3 weeks of amoxicillin. The cat will NOT accept metronidazole. Vet recommends trying fenbendazole to address possibility of giardia or other parasites not detectable on the tests used).

I use it.

Vet finally responded and said it’s OK!

I use it for my kitties. I buy it every year for the horses.
