I think he's in for a bit of a shock
I've normally had all my other cats done pretty early on, but finances and other bills meant I kept deterring it with Bubs, especially since he wasnt doing some of the usual stuff that toms tend to do.
However, with Chaz being ill, its almost like Bub's confidence has grown because Chaz isn't able to be the Boss he used to be.. and over the past couple of weeks Bubs has gradually grown more cocky (pardon the pun).
Chaz used to be able to outwit him, but now Bubs has realised charlie doesnt have the power he used to, then Bubs has stepped into the role of thinking he's become TC, and Im not having him bullying the other 2.
