Daily Nutritional Requirement of Rats

I pulverize their tablets and mix it with
their favorite peanut milk chocolate powder candy

According to research...

Each rat eats = 15g of dry food blocks per day 

1kg of dry food block = can feed 52 – 76 rats 

1 rat = needs 60 calories per day (depending on size)
