Hi, welcome to OUR world of Bengal Addiction
Your boy Oliver is very handsome.
Regarding neutering him. I
STRONGLY ADVISE IT, if you want him to be your indoor PET.
If he is already a year old, you should probably do it SOON. Otherwise you could have problems with him "marking" or "spaying" your belongings, windowsills, doors and doorways.
It is very NATURAL for an un-neutered male to spray. The longer you wait, the greater the likelihood he will start. Particularly if there is an un-spayed female anywhere NEAR where you live. When the females go into heat, the males are MORE prone to spraying.
He will be a much healthier and SAFER boy, if you have him neutered, because the desire to "wander" to find female companionship is greatly reduced.
