None. You can turn off the default responses from displaying though, in the options.
thats better - thanks 
Im also trying to get my pets to respond to the attack using the $target command, but I cant get it to work - but im sure Ive seen another MM's pet do it
Am i just being thick, or is there an issue here?
No otehr MM has done it, since it can't be done - pets can't use variables.
Is there any way to overwrite what the pets usually respond with? Ive tried some binds, but they just end up saying both responses
