Thank the cat gods that's over. Three days locked inside, all alone. Forced to use litter trays. Simply awful.
At least there were three litter trays to chose from, although I only needed one. I found I lost my appetite through the whole ordeal actually. At first I kept coughing up hairballs and then I couldn't keep any food down. So there was quite a lot of food left over.
But I survived. And aside from leaving piles of half-digested food for Ellen to clean up, I didn't make any mess at all.
But I do hope my cat door gets fixed soon!
