I like the little unique twist to this poem, not many would think it was about your dog ha. Well towards the end yes but you'd probably just assume it was your typical love poem but it's not.
Loved the title, fluffballs, ah makes me feel so warm and fuzzy inside. I just love Zena's name, it's so gorgeous, not sure how you found such a beautiful name :)
Of course you always add your own poetic touch - looking like a fluffy rabbit & turning the house into a winter wonderland - loved these! Totally know what you mean.
This is why dogs/cats are the best or any pet for that matter, they do love you unconditionally and make you feel so loved all the time. I love coming home to my dogs and having them love on me and bark because they are so excited. Makes you feel so welcome to be home.
