Yea, uh, Im not going to spay myself because of the irresponsible people out there that cannot afford a child.. Thats a very Crazy statement that you've made and is in NO way at all, even remotely close to S/N a animal! Im appaulled that you would even say that!
No to mention the fact that, Humans will ussually have 1 child every 9 months (Most ussually stop at 3-4 children) Where as dogs cats ect. Can have 4-12 babies TWICE a year! Totally different!
