Chronic Respiratory Problems in a cat?

some of her health problems just sound like old age to me give her soft food for her worn down teeth and brush the little stubs that she has the "wheezing" is probably feline asthma do to being in dusty conditions also her litter box if you put litter that is really dusty she can inhale a partical that some litters have and it eventually causes feline respiratory problems so you can perhaps change the litter and that may help...good luck with her and i hope you can come up with the financial means to eventually take her to the vet but for now just try keeping her in places with fresh air and keep her eyes clear you can try over the counter things for runny eyes too if they have any...
