Am posting this as a response to crewsin.
I came up with an idea, & had planned to post, & it may have been posted b4, but I haven't seen it.
When the eggs are brought inside, always separate the eggs that are 2 or more on a single leaf, cutting carefully with sharp scissors, leaving as much leaf as you can safely for each cat, this will be their 1st mw meal. This will prevent them from eating their siblings or 'leaf-mate' if they were laid by different 'Mamas'
I have taken the bottom half of an egg carton, with the 12 little cups, the plastic carton, not the cardboard, as the cardboard breaks down when wet; placed moist paper toweling in each little cup; one paper towel may be sufficient,rotated for the most coverage; tucked down in cups w/ fingers, (but I always use the selct-a-size towels & have used 1 1/2) , & I made a sleeve to fit snugly over it with toile, or tulle, whichever spelling you prefer, here in the South is often tulle,) & place the eggs you have collected,into the individual cups, on the pieces of leaves, 1 egg per cup, on top of a clean damp fresh leaf for each egg, & slipped the bottom half of the egg carton into this sleeve. If the tulle doesn't fit snugly enough to cover securely each individual cup, a straight pin, thumb tac or push pin can be safely used to keep it down.
This I place on a tray on my kitchen bar, (my own personal way of doing things), this way I can monitor the progress of the eggs & the birthing of the cats. Then, as they are born, I decide when it is time to move them to a 'community container', again my personal way & term. Keep the leaves replenished as needed, then in a day or so, you can transfer the babies to another container of your choosing; each have their own personal preference of container type; plastic Glad ware containers, plastic shoe boxes, which I use sometimes, or covers from cheesecakes or such,(using the cover for the contaner) from local deli is my personal preference, lining the bottom with moist paper towels, which turn up at the sides for easy removal. I always make about 3-4 layers of moist paper towels, rotating the different layers so the corners are easier for me to find. (As I come to the last moist paper towel, I moisten 3-4 more & replenish, on this cleaning. (If there happens to be any 'staining' that has gone through to the one below, I toss that one also. This way, I can lift out the paper towel on top, holding the cata, frass & left-over leaf bits, sit it on my tray, & place fresh leaves on the waiting clean paper towel below.
Then I place fresh, rinsed, moist leaves around on the clean paper towel & place a baby on a new leaf, dispose of the waste (frass) & any uneaten leaf 'bits', & re-cover with the tulle, secured with a large rubber band, or the bottom of the container, now used as the top, with the center cut out & tulle, hot glued in, securely. Some prefer to pat the leaves dry, is personal pref, again. I love to see their little heads going back & forth getting the moisture. Again, your personal pref.
I always try to clean 'before any cats start wandering', so, the possibility of them wandering off while doing this process it isn't a problem. Just in case, I have netting picnic-plate covers to place over them while I get the dirty paper towel disposed of.
I have several of the 'bamboo & tulle fan-fold picnic plate protectors' that I use for community feeding also, using appropriate sized plastic plant saucers as a liner, or plastic plates & using same method of cleaning. You will find your own personal preference in containers, whatever works best for you, there are some very good suggestions & ideas in earlier posts. You will also find the number of cats you are comfortable with in each 'community feeding container' as you get further into the process, personally I decrease the number in a community feeder as they increase in size.
You will also find your own personal method of transferring or handling the cats, whatever is comfortable for you; some use brushes, bamboo skewers, q-tips & other methods. I have long, sturdy natural home-grown nails, & transfer & handle them that way, always washing thouroughly before & after. The cats 'scoop up' on my ring & middle finger, secured by my thumbnail, if needed. My nails are very long & always smooth, & I have handled thousands of cats a year, never damaging one. I also have disposable blue plastic latex-free gloves always handy, that I use when needed. I think all will agree that one of the most important things, besides keeping the cats safe, is keeping their enivronment clean, & frequent removal of the frass (waste from the cats, if you are not familiar with the term), is an important thing for their safety & vital for their health.
I personally refer to the waste as 'castings' since I use earthworms in my soil, for the aeration factor & their 'castings' are a great constant fertilizer. It is a local Southern thing I have always done, they are plentiful here, & a natural way to constantly fertilize. They can be gathered early mornings & late evenings, here in our area, moving about on the concrete driveways & walkways in our yards, (but as I grow in containers, they often find their way into my soil).
There are some that take cuttings of the mw, placed in water in different typed of containers, later in the instar stages & placing the cats on them, making a tent-roll-down-hill of paper towels or some other material, where the frass rolls down the 'hill', for easier cleaning. I ran very short of mw one year & had to resort to being conservative with leaves, so it depends on your personal 'supply & demand' on your method, later in the growth cycle.Leaves or stem cuttings, is up to you.
This is simply a suggestion, & somethings I, personally do, & not to be mistaken as a lesson or instructions of any kind. We each learn new things, it seems, each season, some good, some not so good. So when I visit the forums, it is like going grocery shopping; some things "I take off the shelf"
& make note of for later use, or use immediately, & some I 'just leave be."
Wishing you the very best with your new 'charges' & lots of fun & love. Each season has its tears for me, tears of sorrow & joy, but the good always outweigh the bad. Personally, I simply pray for guidance, wisdom & strength to care for my babies.
God Bless you in all that you do & whatever you encounter, Have a beautiful Butterfly Day...tarheel
