Thank you for clarifying that so well, Karen. I understand (and agree) with everything you said.

One idea is to maybe make the copyright notice on the actual dotd, cotd, and potd pages to make it that more prominant?

And in response to Samantha Puppy:

I don't know about policy or law, what has me so heated is that they're misleading the public. If I were someone in their area and accessed their page and saw one of those cats, I'd expect to be able to inquire about adopting THAT pet in THAT picture.
I take it more to be a pretty cat banner, rather than "these are the individual cats we have for adoption" kind of thing. Otherwise their banner would be changing every single day.

But again, I do think it is disgusting to take what is obviously somebody else's work and make it to be their own (taking the cotd logo off!!!)
