Do you think people who abandon their pets should be fined?

There are millions of pets being abandoned by their owners. Sure some might have good reasons for not being able to keep their pets, such as financial crisis (can't afford to feed the pets), or illness (can't take care of the pets), or maybe no longer have the time to take care of the pets due to work or school or other important matters.

However, in many cases, the owners simply got bored with their pets, or don't want to take the responsibility any more while they are still fully capable of taking care of the pets they bought in the first place. Once in a while, I even saw questions on Yahoo Answers about "How do I kill my fish? I am bored with it"...

Some people dump their pets in front of animal shelters, some people simply drop them off the car on the street far away from home.

In my personal opinion, it is perfectly fine trying to find someone to adopt your pets when you are no longer capable of taking care of the pets due to financial, health, or time restrictions. It is not fine to dump the pets simple because "I am bored with it". It is even worse to just ditch the pets on the street.
When you get a pet, whether or not you get it for free or bought it with money, you have already made the decision to take care of the pet and make sure it lives a good life. Any unreasonable change of mind is bad...simply bad...

This is also my personal opinion that a penalty fine should be applied except when the pet owner is in financial crisis. Yes, that means all else should be fined even if take the animal to the animal shelter. It is ok to give them to a friend or someone else for free or for a fee.

Do you think there should be penalty come with ditching pets without a good reason? Extra fine for those who simply dump their pets outside?
