Quote: They can be carried by various species so it's safe to say migratory birds could introduce it if it's not already there, which I would doubt. It's been recorded in other countries too. They are very rare, granted. Strange that you seem not to have heard of blue pigeon lice, but I too dismissed the idea, for far too long. To the thread starter: my cat also healed up, quite frequently. For years. The huge outbreak only occurred later.
