One Twitter user, Jogchum Vrielink, posted two identical pictures of his cat curled up, asleep, with the caption: “Cat behavior before lockdown vs cat behavior during lockdown”.
Scottish business networking organisation Scotland Europa, based in Brussels, posted a picture of a kitten inside a sporran.
The caption read: “Scotland Europa is open for business today, and this is our feline fighter #BrusselsLockdown”.
The Federal Police yesterday morning put out a tweet with a picture of a cat bowl filled with food: “For cats who have helped us yesterday...here you go!”
MSP Roseanna Cunningham, secretary for Fair Work, Skills and Training, also joined in the tweets.
She wrote: “I *might* be overdoing the RTs on this #BrusselsLockdown thing, but it’s a hoot & the best way to respond to a threatening situation.”
It is thought the trend was started by a Dutch cameraman Hugo Janssen, who tweeted: “Instead of tweets about police activity in Brussels, here’s a picture of our cat Mozart.”
