If you live with a cat inside you're living with the lovely ammonia fragrance of cats shitting and pissing inside your house constantly. After about 4 months a puppy is good enough to not shit or piss in the house, you just let them outside a couple times a day. No big deal.
Cats are fucking filthy. Living with cat shit in your house is disgusting, and you most certainly have to pick it up out of their filthy fucking litterbox which they track cat litter out of and all around the house, covered in cat shit and piss.
It sounds like the toxoplasmosis has gotcha bad, mayne.
