Pasta - I 'think' that it was this stuff

I only have it on one window just now - Frankie is too fat to get through the bathroom window. When he was younger he used to sit on a high shelf and watch the birds in the yard outside the window. I was terrified that he would try and chase them - my flat is on the second and third floors. It is strong stuff.
Are the two felines getting on okay? Dogs are such easy to understand animals but cats are just too confusing.
Good luck - I am off to turf Frankie off my bed and then I am going to have a sleep. Good luck with the netting.
