We did not know about separating the litter box and food and water fountain. All are contained in a bathroom, and our cat just does what cats do. Happily.
I have a friend whose husband had the same heel problem after hospitalization/surgery for a broken neck after a fall. It was a slow process, but my friend and her husband followed all medical directions and he sloooowly healed. He is back driving and playing cards with his friends now. Sending prayers for strength and healing for both of you.
If this is your birthday, Lady Bri, Oh, Happy Day! If not, Oh, Happy Day anyway!
