Today after work I went to Home Depot to get a few more supplies, including a fancier staple gun than the one I bought last year:
I like it because it has a wire guide which should make it easier to staple the chicken wire to the cat enclosure. I also bought stainless steel staples, which my Dad suggested for outdoor use, since they won’t rust:
And I picked up 3 6-foot 1×3’s – Dad suggested 2×3’s but I couldn’t find any. I’ll use them to craft the door for the enclosure:
And galvanized hinges  and door handle [another Dad suggestion since they won’t rust]:
I have tomorrow off from work [woohoo!] so I’m hoping [if the rain holds off] to get the enclosure enclosed in chicken wire and get the door built.
Lastly, I found these awesome seat cushions which are meant to go on chairs but fit perfectly on the enclosure shelves:
They were on super sale [$20/each vs. $55/each on the website], and are meant to be outdoors, so hopefully they won’t get mildewy. I like the subtle jungle print:
And they have ties so I can easily tie them to the shelf slats. Score!
