Oh my! What to do? My husband says all those things to me. His comments started when we had three. You know...This is it! To much hair, vet bills, food, litter, tearing up the house, blah, blah, blah!! Now that we have NINE he just looks at me and says "Why don't you just go ahead and make it an even dozen?" He sounds grumpy too but God help the person that ever tried to hurt one of our kitties! He loves them all too. I know we have more than enough and we really don't have room or the finances to care for any more. BUT I also know that if that precious little stray wandered into my yard I would be in trouble! If I couldn't find it a good home then it would stay. It is so hard to know what to do. I guess deep down you know when you have reached your limit and you will do what you have to do.
My guess is that from the tone of your post...You have a new kitty!! She is adorable! I bet we see more pictures of this cute baby girl! Good luck and I know that it will turn out right no matter what you do!
