The barrier seems to be holding up ok at the moment - I'm quite surprised we've not come down in the morning to find the plants eaten to the stems because of any cats that are about during the night (as ours are kept in)!!!
Ginny is a realy nip-head, and she's already got herself into a routine for the weekends ...
When we let her out in the morning, out to one of OUR flowerbeds, does her business and has a dig, then over to the cat mint, has a rub and a nibble of any shoots that are outside the thing - and then indoors!
