The Bengal breed can be "wild" so make sure to do introductions slowly and only under supervision.

Are your females spayed? I had a neutered male who sprayed when my then unspayed female went into heat.

Make sure to add at least one more litter box, food and water station to curb any problems with rivalry and resentment about sharing.

Best of luck with your new addition. I'd love to see him (the snow bengals are GORGEOUS!)
