I live in a one room space.
13 snakes, 16 breeder rats and around 30 pups at all times.
The pythons are about ten feet from the breeder rats. But when I bring the feeder tub next to the rack, suddenly all heads are popping out looking. Just moving the tub that distance makes them that much more attentive.
I also, do as the other poster noted, and I feed my most aggressive feeders first. Usually as soon as I pull the tub up. I let them strike and swallow, then I feed the less aggressive feeders.
The colubrids are on the other end of the space. They are so attentive to feeding day, that I swear they hear the blowdryer. They are my only FT feeders and they are alert while the prey is defrosting, but as I walk up to the enclosure with the FT warmed prey they are there to meet me at the gate.
