I think it is totally cute.
I've been seeing alot of these decals lately and I love them.
Way better than wallpaper and you can use them so creatively in designing your house.
The ones I have seen and loved is when they put it above a bed for an instant headboard.
I don't feed my cat fish oil often but when I feel like it is really dry in the house or her coat is getting a bit rough, I supplement her with fish oil from time to time. I do notice a definite improvement when I do.
