The garden itself is pretty safe but yes, there are cats in the neighbourhood (including my own). Just googled hardware cloth and it does look sturdier, I'll get that instead. Thank you for the tip!
your very welcome. And I agree, my cat really couldn't care less about my big chickens, however I know he would have LOOOOVED to get a hold of one of them when they were small and more like the birds he gets everyday. Plus, I have seen other neighborhood cats stalking my chickens. None have tried to get one, but again I think that is because mine are bigger than the cats are lol
