what sickness are cause to humans due to cat and dog urine that is so bad we cannot breath in house?

I know there is an infection or what not you can get when you are pregnant if you have a cat, it can really damage your baby. I don’t remember the name of it.
If you were wanting to know what about the dog/cat urnine makes it hard to breath indoors- it is the amonia in their urine. They would have to be urinating a lot inside the house before you’d feel like you couldn’t breath though.

what causes chronic headaches to go away while pregnant, but come back after having baby?

chronic everday headache since jan. 2001. headache starts as soon as get up in morning. pain in forehead,cheeks,upper teeth,nose,temples. pregnant in 2004.In 2005 headaces came back, the same as before. NO PAIN AT ALL WHILE PREGNANT OR BREASTFEEDING FOR 1 MONTH.Matter of fact i felt great while pregnant.!! neuorllogist says tension/migraine type. but tried so many type of migraine meds and either didn’t work or did but came back next day. tried preventive meds…DON’T WORK. feel constant pressure, but not clogged nose unless lay down. can’t breath when lay down. scalp is sore to touch, bending down makes worse as well as cold temperature, and high allitudes.
Heating pad and sleep only thing that takes pain away, besides being pregnant. decongestants work sometimes. (cold/sinus tablets). allegra-d worked for 2 months then stopped. allergic to cat dander, dust, ragweed. and milk.
what can cause sinus type headaches to go away while
pregnant? hormones food allergy?
