I hate losing kits too...don't we all. It usedtoreally bother me when my rabbits were strictly pet and 4H projects. Nowthat I have so many and I breed so much...it doesn't really get to meas badly. Its still sad, and I always wish it to not happen, but happenit does on occasion and It doesn't hurt so deeply anymoreTo lose onekit and have 4 other litters survive...then I still have alot of babies.
So, enjoy the babies you do have, that di make it. Be proud that helpedraise them and be second mommmy to them. Take pride in youraccomplishments, and don't dwell on your losses too long.
