Your responsibilities do not end when you no longer want your pet. Whether your pet has outgrown its enclosure (like a 10 foot python), or you have to move and can’t take your pet with you, you still need to make sure your pet is properly cared for in your absence.
Simply letting animals go is NEVER the answer no matter how adapted the pet may be to living on its own. The media is filled with stories of unwanted fish, snakes, alligators, dogs, cats and insects that have been released into the environment only to destroy it by interrupting the normal food chain. Pythons are eating their way through the delicate eco system of Florida causing several endangered species to be even more threatened. Feral cats are snatching up our song birds until they too are becoming sparce. And even wild dogs form packs in large cities and can be a serious threat to school children walking to a bus stop. All of this is happening because people are too irresponsible to properly manage the care of their pets when they themselves can no longer do it.
Making sure your pet has a home before you give up your duties is a pretty easy task. Unusual animals are probably the easiest to place. Is your 700 pound lion too expensive to feed these days? You would be surprised how many rescue groups are out there able to find him a home. Is your pet monkey too aggressive now that it is sexually mature and views you as competition? Plenty of monkey breeders would love the donation. All it takes is a little effort on your part to find an individual or organization that will find your pet a suitable home. The internet is full of pet rescues. Dog and cat rescues are the most common. These people are dedicated to finding homes for unwanted animals and will place your animal in a loving, well qualified home, even if it is in foster care for a while.
If there just are not any individuals, groups, organizations, zoos, or societies out there willing to take your pet in, then your only other option may be euthanasia. As a last resort this option is awways available and is much better than putting a litter of kittens in a box and throwing it out of a moving car into a water filled ditch. I have had the experience of finding such a box and it was one of the saddest days of my life. Your pets have given you an enormous amount of their time, love and devotion. They deserve to be treated with dignity when you can no longer care for them yourself.
As a last word, please consider these same groups when deciding to obtain a new pet. These pets need you more than ever!
