I am sorry to bother everybody with a new issue, but yesterday was really a tough day. After coming home I realized my table which is next to the playpen was disarranged, the keyboard moved and the worst thing some monitor cables chewed on (fortunately still working). It seemed that Tinto had somehow managed to climb/jump over the fence and get on the table and back. Then in the evening when I was having a Skype call, I witnessed to the same event. The fence is 27.5 inches (70 cm) high but still his legs are strong enough to jump over it if there is something standing immediately next to the playpen. I thought if will be high enough... I am so deluded. I bought and I did everything I could and still it doesn't work. I honestly don't know what to do.
