I have 4 dogs and 2 cats. the lids from the large plastic coffee "cans" are good size for feeding them soft food. they get competitive when soft food is served (1 time a day) and need to be separated. lol. I use the large plastic container that pretzels come in to stand my scissors in. there is a felt pad on the bottom. love this thread! I am jotting down favorites as I read. like someone else said-clean pizza boxes are great for extra and "practiced" blocks
