THis topic gives me one gynormous flash back on the animal warehouse where I worked for a year. I thought I was helping, honest to God, to help the sick and injured, but I will never know. I will not put anything in a cage or tank, ever since. All i can say is if you get it from a petstore, your doing no better than a puppymill.
If you buy from a reputable breeder from rat and mouse on out, then that is better.
If you consider that they will need just as expensive of vet care, that is better.
IF you research out the wazooooo about the proper way to set up a tank instead of rushing home filling it with water and dumping in an assortment of fish, if you do it RIGHT, that is better.
IF you understand that birds and tortoises are a long time commitment, not a temp enjoyment, that is better.
If you understand that birds develop very deep bonds and that often it can tear them up if that bond is broken, that is better.
Read and read some more and then wait, save, and do it right, that would be better.
The whole thing makes me want to go weep.
