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.
Endocrine glands do not form ducts and release their products directly into the blood. As a result, glands can be classified by whether or not they have a duct. Another difference between endocrine and exocrine glands is that exocrine glands are usually much simpler and easier to categorize than endocrine ones.Although they are often made up of multiple cells, exocrine glands may be as small as a single cell.ndocrine glands do not form ducts and release their products directly into the blood.
