My 7wk cat has booger eyes, he has a vet appt in 3days. Is there any thing I can do now?

Along with booger eyes, snotty nose and/or sneezing usually go along for the ride. Until you get to the vet, just take a clean tissue and gently wipe the boogers away, from the inside corner of the eye in a down word movement. Keep watch for loose stools (with or without red {blood}), drooling, loss of appetite, loss of energy.......
