A pet is a big responsibility, so people should fully think through the long-term commitment before deciding to adopt one. For example, dogs need to be walked a few times a day, which can be an impossible chore for some families. A family that spends most of its time at school or at work might have a hard time giving a dog the attention it needs. In such a case, a cat might be a more suitable choice. In addition, vet bills can be quite expensive. It is a good idea for people to determine if they make enough money to pay for the check-ups and vaccinations a pet requires. Many people prefer to adopt pets from their local animal shelters rather than from breeders or pet shops. It is also wise to consider an animal's size. A house with a yard could accommodate a pet of any size, but a cat or a small dog is a better fit for an apartment.
