for the fleas: he is too young to give a bath so you might want to get a flea comb and pick them off that way
How many fleas does he have? if they are covered in fleas for a long time then they can become anemic
Oh and you could try wiping the eyes with a warm damp towel... and the best thing for keeping warm is to put blankets in the dryer and then wrap them up in that!
so good of you to step in .... and i love the name
noel is perfect
did you buy him or was he free?
