Our new children are Thor and Freyja, though only Freyja is caught on camera here. They’re Russian Blues, and Freyja is about 5 months in this video. They are endless entertainment.
While pipe cleaners and crumpled up pieces of paper are favoured, this, ‘the bird’, is the favourite hands-down. They never tire of it (unlike the expensive rotating laser toy that we bought that only provides a minor interest for a minute or so).
