A few months ago, we were given a grey kitten by my brother who told us to look after her carefully (having lost/had stolen) two before her. Naturally, I said we'd take good care of her and I'd try to keep her inside.
Of course, two weeks after we got her, one of the children left the front door open and boom, she was gone. It took a couple of weeks but the children got over it.
Tonight however, a grey kitten with the EXACT markings our kitten had has come inside the house (the door was open to let some air in) and looks about the right size our kitten would be had she still been here. I'm pretty certain it's our kitten who went missing, especially as she's going to where we used to keep her food and litter tray and going mental over DD (she was the kitten's favourite while we had her). The problem is, she's obviously been well looked after and has a collar on so whoever took her (whether or not they knew her origins) obviously now has a bond with her.
I think we should let her go and see if she chooses to come back or not but DD (backed up by DH) is saying that we should go tit for tat and nick her back*. I think it's completely wrong but I seem to be on the losing end of this argument. What do you think?
AIBU to just let her go and see what happens?
*Obviously I haven't shut the door on her to keep her in, I'm holding out on this as much as I can.
