My boyfriend and I have two Bengals, Rishi (tan and black spotted) and Frankie (snow tri-color marble). Their dad was a 20-pounder, but their mom is a petite 12 lbs, so we are assuming that when they grow to full size they'll be somewhere in between. (They are probably both at least 7 lbs now).
Had to get a kitty fountain in order to get our two bengal boys (both under 1 yr old) to stop stalking the bathroom and licking the shower curtain/faucet any time anybody took a bath and also to get them to stop crying constantly for someone to turn on the water for them. (No mere water in a bowl for them...apparently it's much too "common" for their tastes.) So far the kitty fountain is working; they took to it right away!
Can't find any toys that can withstand the punishing force of two bengals...the wand ones I got (which they love, especially with large feathers and bells) usually don't last more than one play session before the string comes apart from the feathers or the wand breaks where it's attached to the string. Very strong cats!
Bengal destruction count so far due to their high-energy playfulness: one large metal living room curtain rod ripped from where it was attached to the wall (bent beyond repair from their tight-rope walking escapades; had to replace it with an extra-strong and much thicker wooden fixture and pole), one large glass decorative vase in a 3-ft stand (completely smashed to smithereens), one front screen door (bent out of its hinges before we could train them not to climb it), one fake tree (all the potting material pulled out and scattered), one broken louver window glass pane in the bathroom (where they jumped on it with all their force, I suppose), one ripped bedroom curtain (still teaching them not to climb that), several broken fridge magnets, a couple of ripped-apart dried Hawaiian flower lei, broken Hawaiian (gourd?)drum, tooth gouge mark in my new cell phone, one wall clock (they kept jumping up in the middle of the night and batting at it until they could knock it off the wall and onto the floor with a crash, despite it hanging five feet above--this happened repeatedly, waking us up from a sound sleep and scaring me half to death. My boyfriend finally held them up so they could examine the moving seconds hand up close--then they they lost interest, lol). They love their kitty tree, of course, but they also love pulling all the couch seat cushions off, and any any napkins, pens, stringy items in the trash are fair game to become "toys" once they cats pull them out or discover them lying about. We even have a picture of one of them, when he first arrived at our house, where we caught him climbing the back door screen, only to become sandwiched in between the screen and the sliding glass door...guess we should have known it was a taste of things to come.
Every morning they serve as a natural alarm clock with their daily wrestling sessions at 5am (thump, thump, thump, thud, crash!) as they chase each other and pounce on each other and slide across the wooden floors and growl and knock things over. They especially love playing the "skid-across-wood-floors-with-wet-paws-dipped-in-the-kitty-fountain" game, and they also like having us humans chase them around as they take turns hiding and then taunting us until we chase them again, kinda a strange kitty version of tag combined with hide-and-go-seek.
To let them get rid of some of that Bengal energy, we have to put them outside (on leashes and under supervision from us of course) for part of the day, and they always growl when it's time to come back in (which I interpret as "but we don't waaaant to go back in yet! Five more minutes, five more minutes! You're no fun!!! Sulk, sulk." One of them is quite the Houdini, too, so I'm looking for another type of leash that he can't squirm out of.) They make little chipmunk noises when stalking their favorite toys, "robble robble" noises when eating their food, and loud meowing constantly at all times in between.
Love 'em, wouldn't trade 'em for the world!
Beautiful dog-like cats that even our dog-preferring neighbors admire and make an exception to their "I don't like cats rule" for! Our Bengals are extremely social and friendly, though they aren't big fans of sitting still or sitting in a lap, and one even strikes up a natural big rumbling motor of a purr in welcome if a human he knows even vaguely starts walking in his general direction, only to plop and roll over to expose his spotted belly for more rubs if the human stops to pat him (Scooore! Bonus! Purr, purr....). They even put up with strange little neighbor children patting them awkwardly on the head in the way that little children are apt to do.
Definitely the most high-energy cats I've ever known after taking care of several non-Bengals though my lifetime...even one of them having a persistent heart murmur hasn't slowed him down that much. Yay for Bengals!
(Just don't have anything decorative or valuable in your house for them to jump at and knock over and break and rip up.
