I love these habitats, they are perfect for bird rescues, and injured birds in rehab. It keeps them safe, they can get sunlight and fresh air. The safest option for hummingbirds that need rehab for release, room to fly and get exercise. If you want to give a gift to a local bird rescue, order this pack, they get injured birds often and need safe spaces for them while healing.

This is the butterfly habitat recommended by most of my butterfly info sources. I like the viewing window for doing presentations to small groups and the dual zippers make it easier to avoid injuring caterpillars or butterflies. Easy to wash and sanitize, dries quickly and stores flat until the next season. I recommend to everyone considering raising butterflies.

Love the size of this cage. I can easily fit at least 2 plants in it. The zippers work great. The poo platters are easy to clean. Both items fold up nicely when not in use. Sometimes I use the platters just for plants in lieu of the bulky plastic ones that come with some planting pots! Love the clear viewing window, especially when children are around. Have purchased multiple times and satisfied with every one.

Raised lots of monarchs in these enclosures. Easy to clean. Zippers work smoothly. Easy to store for the winter.

I’ve been raising exclusively monarch butterflies in similar enclosures in my home on Long Island NY during the last 4 migration seasons, (releasing over 2700 healthy monarchs from August-October of 2020) so I have made a lot of experiences having tried about 8-9 models from different companies with various features, shapes, and sizes.What I liked about this product and why:1. I was surprised that the product came with a full color instructional booklet because it’s the first time I’ve ever gotten one with a butterfly enclosure! It has very helpful info on raising monarchs and swallowtails for novices that I wish I would have had when I was starting out.2. I appreciated that the 2 zippers allow opening/closing in 2 directions (the flexibility comes in very handy when releasing or tagging multitudes of over 20 butterflies at a time) and all the enclosures I’ve seen so far at this price point have had only one.3. The size is optimal... I use recycled soft drink containers with lids to keep the milkweed upright and consistently fresh (like fresh cut flowers in water), and to keep the caterpillars from drowning in the water due to the lid acting as a barrier (the spot for the straw is where the milkweed goes into the water). This arrangement offers the monarch caterpillars a more hygienic environment that better simulates nature where they can (for the most part) avoid walking in their frass/poop. The shorter and/or wider models are too short to accommodate the large stems of common milkweed in a softdrink container.The taller models don’t fit upright in the back seat of my smallish car (Toyota Yaris) without me having to bend the wire frame slightly which could be a butterfly crushing hazard.4. Some habitats have a floor that’s a thicker nylon rather than mesh, but I like this product with the mesh bottom better because it air-dries faster after I wash it (by soaking in the tub w a highly diluted bleach solution).5. The mesh size is perfect because it consistently keeps predators out and keeps aphids inside (and/or an accidentally hatched tachinid larva or fly) from escaping and getting into my houseplants.6. The see through windows are clear (great for classrooms) and handles are sturdy.7. GREAT PRICE! This RestCloud 3-pack deal is the best value for the money that I’ve seen so far. Since it is best to keep different ages/sizes of monarch butterflies separate (so that the tiny newborns don’t get lost in frass or accidentally eaten by the larger caterpillars), AND since it’s of paramount importance to keep eclosing/hatching monarch butterflies separate from growing caterpillars to prevent the disease called O.E., a 3-pack is ideal for maximizing healthy conditions for growing monarch caterpillars.I would definitely order from this seller again if/when I need more enclosures and would refer anyone who asks for a product recommendation to this seller.Two thumbs up!
