Yeah I did feel really sorry for him. I just calmly removed the bottle and hid it from sight and sat back down. He stopped clucking and wandered round for a bit and then came to sit with me. He was a little restless and kept wandering across my lap and back again and then eventually he bit me on the arm. I hadn't moved or anything, I was just letting him calm down on his own. I didn't react to the bite (other than a slight flinch because he caught me on a fleshy bit!) I didn't say or do anything for a few moments.
You're probably right and I just need to ride it out. I just didn't know if there was anything I was doing wrong or anything I could do better to stop him from getting like this (other than avoiding the toys that seem to instigate the behaviour).
I did wonder whether allowing him to continue shredding cardboard boxes was a bad idea but it's one of his favourite things to do (plus it stops him destorying shelves and walls) so I'm hesitant to take them away too. He doesn't normally get frisky with things after shredding cardboard boxes so I'm hoping this is a just a passing phase.
