There are many animals on the streets right now, and in shelters where sometimes they end up being put down. There are over population of animals due to not spaying or neutering. So before you go out and get a pet you should ask yourself and your family a few questions. This will help to make sure your lifestyle is compatible to having a pet. Also discuss with your family, or ask yourself if you have the money to be a responsible pet owner. Owning pets are a long term commitment, and if you are not prepared you should not own animals. Just because you want a pet, doesn't mean you should have one. Pet's not only need love, they need other things. So it is important to make sure your lifestyle can handle a pet in it. If you are not willing to change your lifestyle. than a pet will not fit into your life. If your work hours are long, and you are not able to walk and give your pet attention, and are not willing to hire a dog sitter than this is another reason to forget owning a pet. All pets need attention and exercise.
It doesn't matter if you adopt your pet or purchase a purebred. a pet is a pet and they are a financial commitment. They need regular vet visits, shots, emergency care, and sometimes special food. If this does not fit into your financial needs, then once again a pet is not for you.
Pets can have alot of energy, which means you will need patience and dedication. Some pets will need to be handled on a regular basis. Some need to be potty trained. Ask your self, is this something you can do, or your family can do.
Do some research also, don't just go out and get a pet, so you can brag that you have a certain type of pet because it's cool. Your pet should fit you as well. It should fit into the size of home or apartment you live in, what kind of cage you can afford to fit into your home if need be etc.
Also don't over populate your self with pets, or before you know it you become a hoarder. It's one thing to love pets, it's another to go overboard and stress the animal as well as your self.
Some pets grow, and look cute as babies, and that's why they are purchased. And once they are adults, they require more, food and attention as well. So know from the start that you are in it for the long haul.
If you think you can answer all these questions in a positive way, than you will be ready for a pet to come into your life.
