Case in point was when Mum came back from a holiday in Turkey in 1997. Both Cats took turns staking out the suitcase & eventually caught & had a play with a roach.
One chewed its legs off after a play chase, and the other then arrived and munched the rest of the roach at first sight (was about 2cm long & nice shiny reddish brown).
Still got no roaches in the house.
Have a nice day: Ag
