A 20 gallon tank should work fine for 1.3. We use rat breeding cages (12x18.25”) for our 1.3 colonies and 7.5x12” mouse breeding enclosures for hoppers or temporary/replacement 1.1 or 1.2. All are outfitted with huts and tp rolls, too.

The only real issue we’ve had is when there are hoppers involved -they tend to harass the pinkies. So, we make sure there are no hoppers left in the breeder cage if someone is about to give birth.

Both the rat and mouse breeder cages hold about a week’s worth of lab pellets on top. We also use 500 ml bottles so we don't have to constantly refill them - the 200 ml water bottles only last for 3-4 days. We use aspen shavings for bedding.

All in all, maintenance requires about 1.5-2 hours per week (includes the thorough cleaning).

The ASF’s sound interesting... How large is the average litter?
