Oooh, he's a handsome boy isn't he!  He looks healthy and sounds like he's recovering well thanks to the care you're giving him.  Great that he's fitting in just fine with the others. 

When you take him back to vet, you might want to have his eye dot looked at.  Since he's had it from birth, it's most likely just a pigmented spot that will stay the same.  But in older cats, these sometimes appear and grow to cause problems or become malignant.  Might be good to get an opinion now to see if it's something to watch.

What a handsome boy!  You are such an angel to take him in and take such wonderful care of him.  Sounds like he's recovering well.  Keep us posted on what the vet says, I hope it's all good news!

That is one handsome tiger/tabby cat. He's beautifully marked! I like tabbies myself (as you can see). So glad he's better!
