It sounds as if you have never owned a bengal. They are not your ordinary cat and are a challenge. However, bengals are a unique breed and you have to enjoy them for what and who they are. Mine is 10 years old and understands the word "no." Bengals are very curious and they are into everything. Another thing is that you should not have gotten her until she was at least 12 weeks old. So, she is super rambunctious at this point as all kittens are. Hang in there. A bengal is a bengal. There is no getting around the fact they have more energy than you will ever have.
Ironically, one of the most-asked questions is how to keep a cat off the table or kitchen counters. My reply is LOL
This is what I do. I pick the cat up off the counter/table, place down on the floor and repeat as necessary. It is really a lost cause if you think you can train them to stay off things. Now ... lap. I wish I had a lap cat bengal, but I don't! I love having a kitty laying in my lap.
Most of all, ENJOY your baby! Owning a bengal is a never-ending adventure. Get used to it!
