That is really weird as Buddy was acting funny earlier too! Last week (?Friday) we had the boxes etc. with Christmas decorations all out in the dining room and in the morning the repairman came to fix water heater so I used the baby gate to block Buddy from coming in the kitchen and getting out the door in case the gate was left open (it was). After the guy left -Buddy went outside and I couldn't get him to some in the house all day! He would look at me from the storm door but that was it. Not intrested in eating or even a treat. My husband finally got him in about 8 that evening and he paced and paced, hid behind me I sat on the floor to talk with him and he tried to wiggle between me and the wall. I was worried also tht he was sick. After about 2 hours (and he had slept some) he went and ate and seemed just fine! Have no idea what brought that on as he never has had any issues before.
Happy to hear that Simba snapped out of it also.
