Creepyowl, as soon as you change something significant in your cat's life, their behaviour will change. And luckily so far, it hasn't resulted in Emmett peeing somewhere other than the litter tray.
We've moved twice in the past year and each time we've had odd and bizarre behaviour from our two kitties Russell and Esper. Each time we've explained to them about the move and why we're moving. But nothing ever prevents it. They don't understand it and don't see why there would be a reason to move. Life is good, why disrupt it?
Here's a sample of what my kitties did when we moved. It's a light hearted way of looking at it all. But I know it was all due to the stress of it all seeing everything disappear into boxes and being taken away. I offered my two plenty of treats in our new home the second they arrived. I left them around the house letting them find them on their own accord so that they could associate the new place with positive outcomes.
1) Puffed Up Tail Freaked Out Mode - Those boxes appeared out of nowhere and they're eating up everything and I can't stop it!! I want out! Hang on, I can't get out.
2) The Most Mundane Thing Will Get My Attention - This is one of the few things the boxes haven't eaten. I will watch it and play with it.
3) I Must Do Something to Confuse the Humans - My routine has been messed up without any consultation, thus I will derail them and the boxes that are being fed items from my house.
4) If You Can't Beat Them, Join Them - I will play with all the boxes, including the ones with the lids left open with breakables, daring them to eat me.
5) Hide From Everything - Maybe I'll get some attention and those boxes will stop being fed. When do I ever get fed? What about me? It's always about those darn boxes!
6) Do Something Annoying Every Hour - That will wake up the human from feeding the boxes. They will realise that their plan is crazed!!
7) Eat the Boxes - That should signal that I'm stronger than the boxes and that I should be paid attention to and be told what is going on!!
