In cases where there isn't enough space though, it shouldn't be used. Transferring the animal(s) to another shelter with more space seems like a good idea, instead of killing them.
Perhaps you can get visitors to wear disposable gloves when they are going to handle the animals? A couple of pairs of gloves, each group reserved for one animal, would greatly reduce cross-contamination. You could also encourage local action like hosting a school and family to come round and check out the animals, interact with them and take them outside. This would also introduce some families to potential pets that they could adopt instead of buying ones at the pet shop. Even if they don't take the animals home, they get some air outside the cage. Seems like a good idea, but the costs aren't very clear.
