Pets are really like a part of your family and I really don't think it is weird to grieve over a loss of your family.
I lost a very special dog in February of this year.
And really he was more like a best friend.
His name was Atlas and here is a few pics of him about 2 weeks before I had to put him down.

You can still see the shave marks on his leg where he was administered his last chemo.
I still miss him very much.
