The tree your dad made is VERY VERY NICE -- good workmanship, and interesting configuration. The paw print fabric and the ladder are very nice "touches" as well. Also "peek a boo -- catch your tail and bite it" , is one of my girls favorite games one on a high shelf, and the other on the next shelf below --- the shelves near the top of your tree will be wonderful for those games
A note -- just for future reference -- the longer the vertical run, on a cat tree for a bengal -- the better!
And, even though he has put the sisal rope on two legs of bottom level -- as your bengals GROW -- the rope will be too low for them to use effectively for claw exercise. As they wear out the carpet on those legs above the ropes (and I can almost guarantee you, they will) You may want to replace it with the sisal rope all of the way up to the floor of the next level up.
No criticism intended -- just aware this is all new to you - as it was to me only a few months ago --
My bengals climb straight up a 6 foot tall hardwood post, and another 4 ft tall one, covered in sisal rope :blink:
(And, they are both girls still under 1 year old !!!) They do like different level "shelves" or resting points" to walk back down, after their wild climb (or RACE) to the top <_<
I have photos of a couple of my cat trees I will try to locate, and add to the gallery.
