What about the pink Himalayan salt lamp?

I'm all for it! As for whether it specifically emits positive radiations (aka negative ions) or not, as long as one feels good in its soft, warm, and glowing presence, what's there to complain? ;)

(By the way, as far as actual negative-ion emitters are concerned, I believe there are actual negative ion emitting machines now available for sale out there. I've personally never tried one, but you'll be (hopefully) able to find reviews of such devices out there, I believe. There's also some interesting stuff for "negative ion generator" on YouTube as well. So hope this helps. Cheers!)

Also, I have (anecdotally) come to understand that cats (and even dogs, to some extent) have the ability to transmute negative energy into positive one. Thus, cats, apparently, will normally get more attracted towards angry / depressed people and such (as opposed to positive people), because they are naturally oriented towards transforming such energies. But this is all anecdotal, and I personally don't have too much experience with cats to confirm this per se. And my own experiences with cats (during various moods) have been somewhat mixed; so I believe this needs more researching. Although if you asked me, this information intuitively rings as true to me; so take that for what it's worth lol.
