you know what they say about people that would abuse animals.

and for him to do that in front of you! I can only imagine how he treats peoples pets when he's alone with them.
something very wrong with him... I have a temper at times and I am not a patient person... but there is just no way I could ever hurt my cats. look at them, that animal that is looking up to you, look at those eyes, that little animal that is depending on a human... HOW could anyone lose their temper with that?
there have been a few times that I just get exasperated with one of the cats, not often but sometimes it has happend, when I am trying to give medicine or clip nails or whatever the reason and I look at them....and I just feel how much I love them. that could never be my reaction to throw them agaist a wall. he obvisoulsy needs professional help, and doesn't care for animals.

I really hope you do report him, these animals have rights, to not be hurt.
