YY we have a Bengal x Siamese and he is exactly as you say.
Absolutely loves hair bands too 🤣
He too can open doors and cause mayhem. He also has an annual holiday and disappears for 3 days once a year. My partner once found him walking round a park a mile away and they both walked past each other before looking back and being like ‘what are you doing here!’.
When he was younger and we moved house regularly (students) we lead trained him and would take him on all our travels. He liked that a lot but as he’s older now he’s more settled and has his patch. DP once left the door open when we were in Wales as he left for a morning walk; and he sat there on the doorstep less than a year old waiting for him to return to a house we had been in less than 24 hrs - which you can imagine for a Bengal is near impossible. Super intelligent breed.
Can have a spiteful side if you disobey him - ie, when you have to keep him indoors for whatever reason. He has sat on tables with his paw on a glass and slowly pushed it off whilst staring at you 🤣. Trashed a whole set of shelves once.
He did have a gf when he was a kitten but after that decided he didn’t like most other cats (at least the neighbouring ones I saw him interact with).
Often got into scraps and misadventures. Must have been over a grand a year on average to fix the chap up with antibiotic injections and vet visits.
High prey drive - one mouse every 11pm like clockwork. Thankfully would eat them rather than leave them to run round the house. Did have to pick up the guts every morning but thankfully he always left it in the same place.
Hes high maintenance but wouldn’t change him for the world. He is the most amazingly loving cat. Completely bonded, very caring, will go back and forth from me and me partner in bed kissing us. He’s very fair with equal love in the family. And we just had a newborn and he is so good with the babe. Absolutely respects his space and items, yet knows he’s part of the family - just a very delicate wee thing, Can’t wait for them to be friends when older.
