late visitor

Few days ago...dark, about late,
Bibi suddenly started growling and meaowing like mad.
I looked at him puzzeled (of course , her) to see what was going on.
He was so mad...growling...deep low grumbling, IiieoauuWWwwwwGGGggrgrgr

Then I saw on the table sitting outside,
two staring flashing eyes between beautiful blue-ish fur.
A neighbour cat thought it was nice to come for a visit.
Bibi was not amused.
