The House Rabbit Journal reported that a third of all rabbits who arrive at shelters in the Bay Area are lost, runaways. You can't put a collar on a rabbit and they aren't likely to find their own way home like Lassie. Microchipping would allow more reunions. It takes only seconds to scan an animal at shelters.
Scanners are free to any shelter that requests one.
There's no excuse for not scanning stray rabbits, but right now with so few rabbits microchipped, there's also little incentive in the shelters to think of scanning rabbits. We can change that. Every rabbit reunited, means the end of that family's frantic worry and guilt. Microchipping of birds is common, not only to thwart the trade in stolen birds, but also because the critters can just fly away. The chip carrying a permanent identification code is no larger than two grains of rice.
