UPDATE:
I am sure everything I have mentioned so far did not help my kitties. Throughout all this I have learned so much more about a cat's and bird's health and safety that I wish I had known before. On our way home today to clean and air the place out, we stopped and bought all pet safe cleaning products (to my surprise, they actually work well too!).
When we got home, my husband used the restroom and as an automatic reflex picked up the air freshener and sprayed it. He came out and I instantly smelled it. I'm freaking out because we are trying to get rid of anything that could irritate lungs and that stuff is extremely strong... and then it clicked. I started researching the product, Citrus Magic (Ingredients: Citrus oil), and sure enough it is toxic to cats. D-limonene is a citrus oil. Here is an article about what it did to a dog from a groomer using it in a shampoo and a cat who got septicemia from it. Incidentally, I got the actual pathologist's report on Cougar and her guesses were chemical inhalation OR septicemia. In his case, I'd guess it was both.
Dog almost dies from reaction to shampoo
Citrus Magic even has products specifically for use with litter boxes and people have written reviews that their cats have died after using them.
I am so ticked off. I can't believe all the ridiculous warnings companies have to put on products, but yet, they don't have to put a warning of stuff that is toxic to pets? Even worse, can sell pet products that are toxic to pets?
So then I look up if it is toxic to birds... it is NOT. That explains why the bird was fine. So then what happened to the bird last Wednesday? When I looked up citrus oil and birds, I found out although that's not toxic, tea tree oil highly is. My husband on Wednesday switched out our Air Wick plug in with Essential Oils and he put in a different fragrance. I would bet money one of the oils was tea tree. I called Air Wick to find out the ingredients and all they would tell me is "fragrance and perfumes". Really? That's all you will say? It's proprietary information and they will only give it out if it is requested on a doctor's letterhead. Problem solved; my doctor is going to write a letter for me requesting it.
My Jordi girl is still doing fine at my mom's. We have now gotten rid of all essential oils, all fragrances, cleaned with pet safe products, aired out the place and are running our air purifier with all fresh filters. We are looking forward to Jordi coming home, but want to wait till we can keep an eye on her just to make sure. I've missed 2 1/2 days of work during all of this and can't take any more time off this week, otherwise, I'd have her home right now!
Today, before I learned all of this, I had my chest x-ray done. I'm curious to see the results after 2 1/2 years of vaping. I will share the results with you when I get them, which should be tomorrow.
Thank you again for all your responses, even the ones who were not so happy I was concerned about the vaping. Believe me, I love vaping too and can't even imagine giving it up, but I had to look at it as a possibility along with everything else. I don't want to ruin this, but after reading about the effects of essential oils and knowing that some, if not all, juices contains them, I still can't help wondering if they are emitted on exhale and what that might possibly due to pets long term. If anyone can shed light on that for me, please do. Having said that, I am convinced vaping did not kill my cats or almost kill my bird. I also know I feel better vaping than smoking (and smell better too). And, my mom's severe hacking cough went away less than 2 days of switching from cigarettes to electronic cigarettes.
To my beloved kitties: I am so sorry for not being a more educated parent, but I hope you know how much I loved/love you and that I would never give up until I figured out what happened to you. I hope you will take comfort in knowing I will make it a mission to educate as many others as I can. And I really hope, Cougar, you are finally letting your guard down and showing Saber how much you do love him!!
I will still let you all know what the results of the chemical testing are.
