it probably wont be one rat , they usually live in far greater numbers
like scrit says , cats normally avoid rats at fear of coming off worse
jack russells love the sport of killing them .
on a recent trip to b+q i noticed some wooden rat traps which were no good as rat traps , until i modified them with brad nails . fired through from underneath leaving about 1/2" of brad sticking through to impale under the chin .
like roger says . dont be too fused about how you get rid of them
they have got to go
there was a forty percent rise in the rat population last year alone
and funnily enough a 40 percent rise in call outs to local authority for the rat catchers
my other hobby, among many, is vermin contol
i use gen 1+ night vision on a very modified air rifle and shoot at local farms , mostly rat dispatch these days
hope youve got the blitter by now
all the best

edit :
almost forgot to say
when you catch or kill it
1 , make sure its dead {they can be very clever and play dead} any injured animal can be very dangerous
2 , dont handle it . we all know the perils of weils diesease . i generally stab them with a pitch fork , in order not to handle them
3 , clean down with disinfectant, jeyes fluid
this helps to stop other rats taking over another rats territory
4 , block any holes
hope that helps
