I have had Stripe (male) for about 2 years. We recently added Tompkin (male). When we introduced them they were 1 1/2 years and 2 months. The introduction went well though I don't think they particularly like each other. More of a tolerance. Now 6 months later, their behavior has changed a lot. They seem to tolerate each other most of the day, but at least twice a day, they go Crazy with teeth chattering and lunging at each other. No blood drawn. So is Tompkin entering puberty? Should I wait it out? Or will they need to be separated? They are in a 2x4 with a 1x3 loft. I have two water bottles, 2 hay bags, and 2 food bowls.
