Mawbroon - SNAP! I just came online to find out what the red 'bite like' spots are, which seemed to have appeared on my 2.5 yr ds.
Your description is exactly the same. I thought it was flea bites at first - cat has been getting daggers all day. I even washed his bed sheets (extreme for me these days!).
He has a few in his hairline - oh oh - just read the handy tip below. I think one on his back looks more blistery this afternoon. But, so far, he is not ill at all. Just very gobby and 'funny'. He has, in retrospect, had a temp for the last few days - as he's felt hot - but i thought it was because he had a jumper on! Sack the parent!
My worry, if this is the pox, is for my 6 month old - who has had a temp for the past few days - although she seems better today. Wonder if she's going to get spotty too?! Wondering, like you, if i can spray the pair of them with breast milk?!!
Have you had any more spots appear, how is he today? Very interested in your case - it's a mirror to mine!
He was meant to go to an easter party tomorrow.
