ug, Is it ok, if I feel like a total jerk? Oh.. How do I tell you guys... How, how how... Don't be mad, after being a complete jerk myself... I've thought it over, I'll accept her offer.
I agree with telling your mom you have no idea what happened to them. If she says she has "better things to worry about than the cats", then I don't think she'd be all that concerned if they were gone.
Do the right thing spirit. I think taking BP's offer is best. She even said she'd call your mother and talk to her directly. She doesn't have to say she's from the internet, she can just say she's from a rescue that's willing to help.
I'd have to say that I can't blame those who are getting upset with you. Just from this thread, I see that people are clearly offering advice to you, and you continually shut it down. Why complain and LOOK for advice when you can't take it?
I've had some really rough times in my life. But I never denied help when someone offered it to me.
ETA: If I was on the net to get help for my cats, talking to people, and I knew it would get me in trouble -- I think I'd take the risk of being yelled at if I cared that much about my cats.
