Hello,
as this space is quite small as it is, I have tried to think of the best way possible to make this space cat escape proof as my cat is dying to get outside!! I already have the net and have done some research and it seems self drilling metal screws would be ideal but are they permanent because I am only renting here and don’t want to damage anything/ want to be able to remove it when I end up moving house
