Should pets be treated like family members?

Hi everyone, this is a toefl exercise that I tried to write. There might be a lot of mistakes and some odd-sounding things. Can you help me correct it?

Should pets be treated like family members?

Nowadays, living with domestic animals such as cats and dogs is quite popular. Almost every Thai family has pets (or: a pet). Some say these pets should be treated like a person who lives in their house. In person, I would (have to) disagree with them for several reasons, namely uncontrollable behaviors, financial stabilization, and unhygienic environment.* 

Many families who live with pets tend to find it difficult to cope with their good and honest furry friends. Actually Some pets are not as domesticated as they seem. Cats, for example, can ruin their owner's estate/home by scratching, tearing, or urinating where they shouldn't. They are animals, after all, who cannot/do not understand human orders. Therefore, it seems irresponsible to treat them like a person.

Financial affairs are an obvious reason why there should not be the same standards for humans and animals. If people raise animals like they're human, they might spend all of their money on their pets. High standard food, medicine, and accessories cost a lot of money. As a result, owners may not be able to afford their pets, or they may sacrifice some of their family's needs in order to provide for their animals. it may have no reason for taking care of them such a way.

Hygene is another concern. Pets can create an unsanitary envoronment since bring about improper hygiene they are often exposed to dirt and dirty floors. They carry a lot of germs and then people play with them, hug them, and let them climb on their beds--which should be kept very clean. By doing this, people can get sick (from the germs their pets carry.)**

In conclusion, I do not think pets should not be treated like a person or one of your family members. because of the fact that They are not a human. If they are treated as such, it will be only be expensive may even harm the owner's health.

* A better way might be: "I would have to disagree with them for several reasons, namely behavioral, financial, and hygenic.

** (from the germs their pets carry.) this might be a little redundant, but it's ok too.

I'm sure my grammar is not perfect, but I hope it helps!
