I know the feeling so very well.
It sounds great to tell friends that my bloodshot eyes and exhausted expression is because I've been kept up all night by a beautiful, energetic, 16 year old girl called Suzie especially when you get to my age!, then I have to explain that she's covered in fur, has four legs and likes nothing better than to rub noses, sink her claws into me and dribble all over me and, suprisingly, they then think I'm very strange
.
Apparently there's a name for people like me (us), "ailurophile(s)", I tell them that I'm an ailurophile and, for some strange reason, they start to reach for their coats and mumble something like "is it really that late already?" !!
.
As the quotation goes : "The more people I meet, the more I like my cats".
Cheers
