The correct answer is option 2: Cattle.

Foot-and-mouth disease is a highly contagious viral disease that affects cloven-hooved animals such as cattle, sheep, goats, and pigs. It is caused by the foot-and-mouth disease virus (FMDV).

Option 1: Cats - Cats are not typically susceptible to foot-and-mouth disease. The disease primarily affects domestic and wild cloven-hooved animals.

Option 3: Dogs - Dogs are generally resistant to foot-and-mouth disease. They can contract the disease in rare cases, but it is not a common occurrence.

Option 4: Poultry - Poultry, including chickens, ducks, and turkeys, are not typically affected by foot-and-mouth disease. The virus mainly affects mammals, especially cloven-hooved animals.

In summary, only option 2 (Cattle) is infected by foot-and-mouth disease.
