Has anyone come up with a good solution for liners to use with the hatchling tubs with the cup holders? Brian Hahn stopped selling the cardboard liners that were custom-fitted to the tubs with a cup holder hole. All my hatch dates are in August-September but I haven't been able to come up with anything more clever than folded over paper towels. It would be great to come up with a snugger solution before the nursery rack starts to fill up.
Thanks for any suggestions, and congrats to all you posters whose animals clearly got busy earlier in the year than mine -- some amazing stuff being shown on this forum!
