There are some videos of cats stuck inside of bird cages, but none of them show how the cat got in there in the first place. (I won’t use a video if I think someone purposely set it up.)
But here’s a young cat who enters the parakeet’s cage to get a drink of water. I get a sense that the parakeet doesn’t quite know what to make of it. Anyhow, this cat’s small enough not to get stuck.
That’s pretty amazing. The bird didn’t seemed to happy about it, but I think that kitten just wanted a drink. How I love God’s creatures.
