Thankyou all so much for your lovely replies. Tipsy and Nemo do get on fine but Tipsy is very boisterous as he is still young only 15 months and he does go over the top when playing with little Nemo he really trys to make sure Nemo knows he is Top Cat, this ends in little nemo screaming usually, so we always supervise especially as Nemo unwell at the moment.. Just got to fatten him up a bit...Thankyou all again XX
