We're going to be moving in 2 weeks. Moving 30 mins away to orange county.
Since our moving day is on the week of Spike's 50% water change I decided to move his water change from monday to the day of the move (weds/thurs).
I was going to cup him/empty his tank 50%. His tank will be fastened in the back sit and I will hold him in his cup.
That should make it easier. If you just keep an eye on him, he should be fine. I travelled over 8 hours this way and Fabio was fine. He was even eating on the trip. There is no way to stop them from moving entirely, but I felt that holding him firmly in my legs helped.
I moved with my late boy Bacardi 4 hours to our new home.. He was great! Put him in a cup in the cup holder and we went on our merry way. Goose my other late boy did the same trip with me a year later. Both boys did great, yours is also only a half hour so i'm sure they will be fine.
