What can I say Kim that others haven't already.
I am in total agreement in what you are doing. Afterall, you would be of no use to the cats if you land up seriously sick and aren't able to care for them. Your health comes first.
Fostering 60 cats is a great accomplishment and you have done a superb job with all of them. More so than what others would have done. In as much as I love cats, I don't think I would have been able to go through the lengths that you did.
You and your hubby have seen to it that these babies have found good, loving and caring forever homes.
I know it hurts to see them go, but it is also rewarding knowing that they will be well cared for, thanks to you.
Take care of yourself Kim and don't come down hard on yourself for what you are doing, cause we sure don't.
We all totally understand and fully support your decision.
