I couldn’t help sharing this. My wife found this while messing around on Etsy.

That is just hilarious.
humm an interesting find but to me it looks like a hair band on a cats neck.
With a pin on it.
Although this does inspire an idea, proton packs for cats. It would be adorable and cause the internet to explode.

Oh man! If anybody does get around to creating then, PLEASE post a pic here. LOL!
In addition to the proton pack for a cat, how about a Ghostbusters uniform for a cat? LOL! Now, that would just be awesome! Our cats would probably hate us for it, but they would look hilarious. 
I have one 75% complete for a miniature dachshund, so it’d work for a (my) cat.
how about a small dog? I want to (if I have the time) make her a slimer costume. im surprised there not one already for pets.
Ha! I was actually thinking about making a pack for my dachshund. I think that would be more likely to make the Internet explode, than some smelly cat.
