Step-by-step explanation:
The most formal way to describe your pet in a letter to a distant relative you have never met might be: "I have a cat and a dog as pets. The cat is intelligent, while the dog is well-behaved." This description conveys the necessary information about your pets without using casual language or making negative comments about them. It is important to remember to be respectful and polite when writing to someone you have never met, especially if the relationship is formal.
