an imaginary, very pleasant place where a pet is believed to go after it dies, and where its owner hopes to see it again when they die

Many people refer to "going over the rainbow bridge" when they share news of the death of a beloved pet on social media.

The grief-stricken owner wrote that her cat had crossed the Rainbow Bridge.

"When I get to that rainbow bridge, there are going to be a lot of dogs there to greet me," he says. 他说：“当我到达那座彩虹桥时，那里会有很多狗来与我相逢。”
