I haven't been a member for very long but it is easy to see how much everyone loves their furkids. After reading your last post I felt my heart break for you. We have 9 furballs now because I can't turn any of them away and after caring for them (even briefly) I can't bear the thought of giving them up. Even if it is to a loving home! Financially we have reached our limit (not to mention space) and that sucks. It sounds like you are going above and beyond the call of duty now with a second job and all. It is so hard to love these little critters and want to give them what they deserve only to be stopped by the almighty dollar! I will be in the same boat if another lost furry soul comes my way. The only comfort is knowing that when the time comes for a decision you will make the right one. You have to do what is best for you and the kitty.
Good luck and I think God sends special blessings to those who care so much.
