I'm going to get fried for this...
I don't think it's fair to assume she is leaving them alone. Yes, she lies every time she opens her mouth, but Destiny doesn't, and D has a very simplistic, sentimental attitude towards pets - we've seen before she'll throw shade at AL, and I think her conscience would jab her into somehow be letting known this is a lie if she's NOT looking after them. More interesting is the "getting paid" - may not be true, but didn't Dumbo realise that just saying it would give the lie to this supposed great friendship she and Destiny have?
I've already said it's wrong to leave cats so long when they are used to your enormous, visible and loud presence constantly, but I think we may be reaching to assume Destiny doesn't go over. More likely once a day (who the hell imposes on someone to drive that far though? God, Amber is solipsistic) and I could be totally wrong. I just don't think she'd go along with such an obvious, open deception a) cos she "loves" them and Amber likely uses this for guilting and b) cos if it's a lie and found out, she'll get the backlash too. She's obviously over covering for Amber. Or maybe I just hope so :-/
Otherwise, everything re animals I agree with you all. Get a pet and you have to adapt, not expect the animal to or just get tossed. And if she was on a warning Wasabi didn't like other cats, why get more? Real animal rescue is not just picking up anything you happen to think might be a stray, it's looking after what you already have properly. Soz for PL but its an example; my cat would hate another one. She's used to her and me and doesn't do sharing. So I only have one cat, who is never left more than three days and has a neighbour checking in on her for those days. AL picks and chooses to suit what she wants to do and fuck anything that gets in her way.
