People in school say I smell? Possibly cats do this?

Your home is very unsanitary, I cannot believe that your parents do not get involved in solving this problem. Bacteria living in the alkaline urine salts also produce ammonia type odors, these strong odors have no doubt affected the sense of smell due to odor damage to the olfactory senses. This strong odor is hardly detected by any one living in this unsanitary condition.because of damage to the sense of smell. If a stranger or other guests come to your home, they would no doubt fall over at the front door from the overbearing ammonia gases coming from the urine. Nothing will change until the cats are removed, the carpet and pad removed, and the floors sealed. Hopefully there are no babies or youngsters in this faulty environment.
