Chicken wire (Dresden ST3)

Hi I have 3 cats and I try really hard to keep them indoors but they keep sneaking out I’d really love to make them a cattery to keep them safe . Please if anyone is gifting any chicken wire I’d be so grateful . I’d like to make a big one or if anyone has anything that would be suitable for the job . I can collect I’d like to make a 50 ft long and 3 ft wide and would be so grateful I know it’s a big ask :)
