For the eye issue... Maybe cleaning daily would help till you take him to the vet? Gerber baby water did wonders for Zoey. She had issues with eye boogies and had slight infection before. But it's gotten so much better since I've started using the baby water along with her daily grooming.
Thank you for fostering. I sort of wonder though... would you be able to let him go after you get attached to him?
I know I won't be able to. I don't know how the foster do it!
