This month we are under the sign of Cancer, the fourth sign in the zodiac.  It represents those born between June 21st and July 22nd.
Cancer is domestic and love the comforts of home, they want security yet seek new adventures. Cancer is extremely loyal with those who appreciate him/her.
On the negative side, the Cancer is grumpy, self-pitying and hypersensitive.  They are complex, impulsive, unpredictable and full of contradiction and need continuous backing and encouragement.

The crab is the symbol of the Cancer, and like the crab the Cancer is quick to retreat into its shells (or home) if it suits its mood.

Said that you should now understand why Mr D. Tail is nearby to his sweet home yet tempt by sea adventures.
