Has the ground and the things touched by the father's hand become impure, and what is the ruling concerning the things bought by the father while his hand was wet with disinfectant?

If an animal is halal (definition) to eat, its waste products are pure, and its eating of these waste products does not make it a jallalah; for a jallalah is that which eats impurities. A jallalah is an animal that follows and eats impurities, meaning any animal that has been fed on impure substances. The urine and dung of an animal that is halal to eat are considered pure by the majority of scholars. Therefore, an animal’s eating of its own waste products does not make it a jallalah, unless that becomes the predominant part of its diet.
