Wally's not eating...

After we came back from the clinic, Wally was so moody and tired. Is it due to the vaccin or he was angry we brought him to the vet or his back was painful after the vaccin??? That day, he refused to eat dinner and even his favorite fruit time also not interested! Quite unusual? Thank God, he was back to normal the next day...

Wally: I'm on diet today since Dr ling said I can't afford to put on any more weight!

Wally: Mummy, please don't force me I don't feel like eating!!! Take it away....
Sniper: Can I have his share????

Wally: How come Coo coo still so interested in food after vaccin???
