I know I dont have a large sample size with only 11 snakes but all 11 are in enclosures that are deemed "too big" and I have had no issues. Do I think that there may be snakes who would be stressed by a larger enclosure and not eat? Yea im sure there are some but I would also bet that theres more to it than just the size. Just bc an animal can be kept alive and healthy in a small space doesnt mean its most beneficial. I like to give all my animals the best life possible and to me being stuffed in a 6inch high tub thats got just enough room to move around isnt considered the best life. I dont hold anything against those people who choose to keep their animals like this its just not my style.
