What are the health effects of breathing cat urine odor 24 hours a day for over a year? There are a total of 6 cats, 4 are kept in an enclosed sun room connected to one side of the entire house with windows between the house and sun room, the waste was rarely if ever cleaned out for over a year. NONE of the 6 cats are fixed so they 'spray' constantly. Standing outdoors near the the room the odor is very strong, just as strong as it is inside the house. The other 2 cats live inside the living quarters of the house. They have a litter box, but it is cleaned so seldom that the cats will urinate outside the litter box all over the floor near the box after two or three days of it not being cleaned. At best the clumps and feces are removed once, maybe twice a week. Their son decided to move out of state and 5 of the six cats are his and were dropped off on his way out of town and just left there over a year ago.
The odor outdoors is strong enough that it can usually be smelled from outside the house next door even though the room is completely on the other side of the house. I can not stand to smell the odor outside of the room, and inside the room it is unbearable to me.
Are there any health dangers for the two adults and two children living in the house? The reason for asking is that I am concerned about the possible long term possible health effects on the two children. Plus, beginning three months after the cats arrived the female adult began having breathing problems. They have gotten steadily & progresssively worse over the last year and now she can barely breathe or walk. Before the cats arrived she had no breathing problems. I am wondering if the cat urine could be the cause of her breathing problems.
Does anyone know anything about this issue or know of a good source of information?
