Freeze-dried chicken snacks
The Freeze-dried chicken snacks, otherwise known as " Treats " are dispensed along side with Kibble.
Appearance
The Freeze-dried chicken snacks appear as white cubes, as it is plain chicken. They are a favorite of Mr Snack and is eaten exclusively by him. Other cats also enjoy it better than the average Kibble, as if you go on a stream at any point in time, chances are that there will be more Kibble (sometimes gets really bad, like Mount Kibble) than Snacks.
Frequency
The frequency of them being dispensed is not very often, yet they run out faster than kibble as seen by the percentages in the information bar at the top-down view of the camera. This is presumably because of the fact that most of the cats prefer the Chicken Snacks over the regular Kibble (as mentioned in Appearance).
In order to dispense them, you need to donate to the real Hello Street Cat stream, exactly like how Kibble is dispensed. We would assume they'd cost a little more than the average Kibble, but most people here don't view the native Chinese streams, so that has yet to be confirmed.
