In case anybody purchases the big canister (300 g), please note the difference in size of scoops between the small canister (50 g) and big canister of this product.

Make sure you are using the correct dosage for your cat. 

I was using a small container for 2 of my cats.  Thought they would be on it long term, so I purchased the big tub of it.  The big tub has a much bigger scoop.  The directions attached by vet office on both tubs said use 1 scoop.  There is a HUGE difference between the scoop sizes.   I had to point it out to the veterinary staff.     They were unaware.  Yikes.

The dosage goes by the weight of your pet.  My cat does not currently need Epikatin.  He has been doing very well without it (with vet approval).  Knock on wood.

Again, this was my local vet office that had the wrong dosage.  The product itself had the correct dosing information on it (under the label that the vet office attached).
