" How would you like it if someone locked you in a bedroom for your whole life and gave you dishes of food three times a day? "
Well, as long as I had these things:
1. DVR
2. Cable TV
3. The dishes of food being my faves, which are BBQ, fried chicken, and Chinese. Pair that with coffee, tea, beer, and bottled water, and I am set!!!
4. My treadmill.
If I have all of that, I will never leave my bedroom!!!
HA HA!!
In all seriousness, I do hear ya and respect what you are saying, but if you are providing your snake with all it needs, like food, clean water, cage as spacious as you can provide, and shelter in the cage, and he is thriving, he is living a great life!!! You have already accomplished what every pet owner should aim for.
This idea of " cruelty " while being in captivity, can not be applied to your situation, if this is all indeed true. Everyone here has made great points that should be pondered.
If you just simply want to get rid of him, find him a good home. Let a kingsnake hobbyist take him for you.
Take care!
