What improved nutrition, basic vet care can do

This is one of my foster cats (Squier) he came from a neglect/hoarding situation. He and his housemates were on the brink of survival, foraging for food as owners had no money to buy food. He came to us in October, has had basic care of treated for fleas, mites, worms and neutered. Steady, high quality food and clean water. Our only remaining problem is a reoccurring eye infection (would love some opinions!) We have used neo eye drops which clears it for a short time.

This is Squier approximately a week after coming to us, late October

This is Squier now, surprise he has long hair! You would never know he is actually still on the thin side, just ultra fluffy!

It could be that he has Feline Herpes.  Was he checked for that.  Many cats have it, and what people normally do for it is to give them L-Lysine all the time - 250 mg twice a day.  Then, during a flare-up, up the dosage to 500 mg twice a day.

Here's a thread on it:  http://www.thecatsite.com/t/239337/where-do-you-buy-your-l-lysine

Ah! I honestly don't know if he was tested, another volunteer took him to the vet and I haven't gotten the notes. I just know she brought him back to me with eye drops!

Thank you for the info, I'll read up and try it
