Hi, my cat got run over at the beginning of lockdown and dislocated his leg. Cage rest for 6 weeks and had the same set up as you’ve described. He couldn’t tolerate a cone so we got him a little body suit thing with a hole in the bum area which worked really well (he hated it for a day or two and then got used to it) other than that, we just made sure to pay him lots of attention, giving him plenty of strokes and love and then after a week or so and he was feeling a little better, we gave him toys to play with in the cage and then again after a few more weeks, he came out the cage for a minute or two a day to have a little stretch and sniff around the living room
