Honest question, is your BSH a sh!thead.?

My husband and I are staff to two shorthairs. One is 2 and a half and the other four. From the same breeder so they are half sisters.

Both of them have proved to be remarkably resistant to training about not getting on to kitchen counters, living room tables, or stealing food either from us or our other two cats.

The youngest also has a remarkable trait of hanging on to trouser legs for attention.

We love them dearly, but would love some tips for ways to teach them better behaviour. Our other 2 cats are much more well behaved and rarely need to be told OI!
