I am so sorry about your kitty – that is a beautiful picture of Nova. It is so hard to lose a person or a pet.
In 1994 I lost my 12 year old blue female chow I had had since she was 8 weeks old and a friend sent me a frame with a place for her picture and a poem on the other side. Which even today when I read it it brings tears to my eyes. Here is that poem
MY HEART BELONGS TO A CHOW CHOW
That blue black tongue
That fluffy mane
The Chow Chow stands apart.
Devoted, proud and loyal,
it stole away my heart.
A dog that always loves a hug.
And often make me grin-
My Chow Chow means
The world to me
My dog, My love, My friend
Even though this is about a dog the words, meanings and feelings could be applied to any pet cat, dog or whatever.
