is my cat getting an upper respiratory infection ?
he's keeps sneezing & has a running nose , how can I treat it.
You don't treat it; you take the cat to the vet. It could simply be allergies or something worse.
Cat does need to go to the vet. Also If u do use cheap cat litter they inhale the dust sometimes & get a upper rest. Infection in there lungs. Good luck with your pet it depends on u for help.
Don't risk your pet's health (nor anyone else's) and go see a professional vet / doctor ASAP.
