Ok so here's some cheap ways to get jars for those males:
Plastic cups: Like 24 to 32 ounces (so about a quart). You can 50 CHEAP!!! Plus if one is infected you can throw one out and have another 50 to replace it.
Food containers: LikeGladware containers work great. A bit more expensive but still worth it.
Mason jars: You can get these things for about $10 for a case of 12. Awesome right :)
Pickle jars: Saving pickle jars can save a lot of money. Just rinse them out really well before use.
Pasta sauce jars: These work great too!! Just be sure to rinse thoroughly.
