Amy is a great person. She among others, myself included, are simply weary of Tikeya's mom's"collective" tendencies. She wants every kind of pet there is, I bet if they made mini elephants she would want that too.
I am not doubting she IS trying with Cheeko
BUT she has alot of help and she automatically takes defense to it, likes she does with everything. Logan did not say she would barge in here and take Cheeko and neither did Pops.
I just hope she does get some help with him IF she is serious about helping Cheeko.
I know she has stated again and again and again that is isn't 'freakin' out when she works with him, but animals can sense when we freak out even if we don't make a big deal out of it.
That is why our animals can sense when we cry, are angry, or are depressed.
It is quite possible that Cheeko might be terrorized past the point of taming. ( and no I didn't say that she is terrorizing him before you go saying that I did) but the incident with the dog and other things probably all led up to it.
