Best Answer: Yes. All the vets & animal charities tell cat owners to keep their cats in at night. Far more cats are killed on the road at night, and more cats are stolen then.f you live near a busy road or in a dangerous area for animals i would keep it inside. However if you cat loves to be outside at night and you live in a safe area, then no, it's not cruel :) Hope I helped xx. Source(s): Personal Experience.
â¢ The main difference between the endocrine gland and exocrine gland is that, an endocrine gland lacks ducts and remains as blocks of tissue. â¢ So, endocrine gland secrets chemical substances directly to the blood stream, while exocrine gland secrets its product into a duct.
Difference Between Exocrine Glands and Endocrine glands. The endocrine system controls the body activities by producing chemical substances called hormones are chemical messengers, secreted by ductless gland known as endocrine glands. Exocrine gland secrete their products into ducts or channels, that carry them either to the outside of the body or into body cavities.
