Rudy the Parrot hates him.
Last week, Rudy tweeted: "They can try but they will never get to me. Birds live twice as long as cats, sometimes longer. @Sockington will perish."
I am sure that is true. However, whereas in January Sockington had 10,000 Twitter followers, now there are more than 500,000. Rudy is stuck on 1,573.
Sockington is, as you have probably guessed, a cat. One extremely popular cat.
