Does this look like a flea bite?
Helloo - we definitely have fleas in the house as we took in a rescue who was riddled with it. I've done my best to keep them split up but clearly the fleas ignored my requests! I've retreated all 3 cats with flea treatment and I've been boiling as many furnishings as I can. He's my only cat with a white ear so I haven't seen this on any other.
