Re: mysterious pests inside
The only thing I can offer is that if you suspect that this is an interspecies toxin, that you consult with a bird and feline spe******t and learn what specific pathogens can be passed between birds, cats, and humans. They may also be able to tell you how to take samples and where to take them for testing. Once you've got that, consult with a physician and ask for the specific tests that will indicate whether those pathogens are in your systems or not.
Until further confirmation can be made and you believe that the house is the cause of your ills, GET OUT!! Living in a toxic home until someone else can confirm your suspicions is only hurting you. If you leave and get better, then you know for yourself that it's the house and not psychosomatic. If the home truly is the problem and the health effects are as severe as you indicate, leaving for only a short period of time should relieve the side affects of a toxic environment. Stay in a hotel, with family, or friends for a week or two and see if you have any noticeable differences.
