You all might remember back in November I bought Bet this little treat ball. You fill it with kibble and when she rolls it around on the floor, kibble falls out.
Being she is a Border Collie (even one that has renounced her 'Border Collie citizenship'), I rolled it around on the floor for her a few times to show her how it worked, she figured it out right away and she has gotten many hours of entertainment from it.
X discovered the 'treat ball' the other night and this is how he solved the problem of getting at the kibble inside.
Siberians are so literal.
