I really don't know where I stand on this. I think PIF has good points and I am concerned about Simba - all it takes is one second of turning your back and there could be a bad accident with Simba and the cat. On the other hand you sound like you are really thinking this through and your dedication to your pets is obvious. I also think of the alternative for the cat. If you plan to adopted an older cat from a kill shelter you may be saving it's life. I think your plans are better than being PTS for sure, as long as Simba isn't a problem.

I have one concern though. You are 16, right? Well do you plan to go to college in two years? If so who be taking care of your pets and if you plan to leave them at home what will happen to the cat? Will it be abandoned to the outside run until you come home? If there are no issues of you going away anywhere then I think it might be okay.

I'm just not sure on this. People have brought up some very good points on both sides.
