I couldn’t find a subject I liked for an extension tube vs no extension tube comparison. I tried the sweater I’m knitting but meh. But the cat was hanging out on his perch and didn’t seem too stressed so I took a picture. And then there was mourning dove hanging out on the air conditioner’s cage bars (that window has bars on it I guess because it’s next to the fire escape but since the air conditioner is there, the bars create a box like shape at the bottom; makes a good landing spot for birds). So that’s all.
