I make these little tents for all twenty of my lovebirds out of tissue boxes and fusable fleece.  Ten of them can be made in 30 minutes once you get the hang of it at a cost of about $2, so you can dispose of them as often as you like at that price.  They are safer that the ones you buy because the fleece being fused to paper means they don't fray, so their little toes don't get caught.  I made them for them at Christmas & put presents inside along with these popcorn ice cream cones.  They sent this card & signed it.
