Glad to help! Funny - my other half says he once thought hed never be able to keep a cat in a flat ...I suppose its just a question of adapting. When we did have guinea pigs, our cats then never seemed very interested and left them alone. Not sure how the current two would behave ..... Chloe would probably sniff and then leave alone - I fear Mr T would want to play!! Although he is 15, going on 16 he behaves like a daft kitten sometimes.....
