You may be close, and the farthest ever from understanding the 'link'.
Although the cat could be the source of your psoriasis, it is far from being "cats cause psoriasis". You must understand the imune system, allergies, and also understand how much isn't yet understood concerning that portion of the body.

For all that it matters, as an example, you could have undiagnosed celiac which means your flour and gluten riddled diet is ultimately the cause of your psoriasis and it simply demonstrated about the same time as the acquisition of the kitty.


I do not currently own a cat. I have owned multiple cats in the past.

I developed psoriasis about 1 year AFTER giving up my last kitty (rabbit, dog, fishes and birds) because I had to move.


I am allergic to just about everything, as listed below. I refuse to not do what makes me happy.

I have psoriosis.
I am mildly allergic to life.
I am severly allergic to most labratory created dyes and scents. Natural ones I have very few problems with. (ie, herbs and essential oils ok, expensive designer shampoo or perfune is not)
I have seasonal allergies year round. Most allergy sufferers are sensitive during one or two season, I get hammered all four.
I have mild food allergies which cause digestive upset, but not severe responses.
I tend to respond more severely to insect and animal interactions, swelling more with mosquito or bee stings than other people, develop rashes if an open wound comes in contact with anything dog, cat, rabbit etc...

I have been this way for 33 yrs.

I developed psoriasis aboot 7 yrs ago, during an in-between period of owning animals. (cats, dogs, rabbits, fish, birds) The psoriasis grew steadily worse and I feared I would go bald from it ( I am mostly afflicted on my scalp with spreading past the hairline onto my neck and forhead and patches which appear elsewhere as they wish )

Had an abnormal pap about 12 yrs ago immediately after the birth of a child. (normal occurance post birth) followed by a normal pap.

About two years ago, after much research and lifestyle changes and the purchase of my first pet in 5 yrs, my psoriasis has steadily improved with only one incidence of briefly worsening when I went back to old ways at the request of my spouse. (Didn't like the way my hair smelled when it was wet and wanted me to use 'regular store bought' shampoo.)



Please keep in mind as you look for your link:


The immune system is like the finished product of an extremely complex cake recipe.

Having an allergy is like altering the ingredients in the cake.

Sometimes, the alteration is barely noticeable. Sometimes the alteration creates what appears to be one thing but is actually something else. (like if you decrease the sugar you may taste more salt and think that was what was altered.)


The things that have helped me the most were not removal of the animals but a focus on making my body balanced by controlling and adding or removing minerals/vitamins/metals in my diet and controlling exposure to known allergens.

A little bit of hard things in life develop character but a lot will break a person. Same for your immune system, a little exposure to an allergen is good, a lot can have diverse unintended consequences as the immune system literally breaks.

My point in giving my extensive allergy picture, is that for you it may be cats, but for me, it is much larger than that. For both of us, I believe the occurance of psoriasis is due more to over exposure to allergens, which created a state of hyper-allergic-responses in our bodies and demonstrated itself in the form of angry itchy painful red welts under skin layers which seem to grow faster than they can shed and underdeveloped new skin which now can not provide it's intended purpose of protection to our bodies at the site it is most needed. The swollen patches of psoriasis.



Disclaimer: My analogy of the immune system and recommendations do not apply to anybody who is dealing with an anaphylactic reaction of any sort. If you have an anaphylactic reaction do not entertain the idea of allowing even trace ammounts of that allergen in/on your body.
