Which animal actually chews its food?

Have you seen a cow or a buffalo while they eat? These bovine creatures chew the grass,"chewing the cud" as it is called. After chewing it they swallow it and later on regurgigate it when restng and start chewing it all over again.I suspect that the animals in the cat family too chew their food before swallowing it.

Cows chew the cud. They gulp first and chew it later when they rest.I think all ruminatory animals like cow and buffallo chews the cud. They do not swallow like other animals.
