My degu has a poorly eye :(

Hi guys,

My degu has a poorly eye. Its got a bit of  white gunk around it and he can't open  it very well. Hes had it for about a day and a half. I've wiped it gently with a piece of damp cotton wool but its not improving.Hes acting normal, he does however have cataracts. I'm at university full time and cant easily get to a vet :/  Anyone experienced this before with their babies?
