Hi,

 When I am petting my cat and she seem very relaxed and contented she
will start sucking on the back of her leg like she is nursing, why?.

 Me and my cat are very close, my wife says she has never seen a cat
so devoted to anybody.  My cat almost always has to be in the same
room as me unless she is taking care of cat business or hunting.  She
even calls out for me if she can't find me right away (even my wife
recognizes the meow that is meant to summon me).

 Oh how much tv is too much for her?, should I limit her.  She like
animal planet best.
