I have 2 males, both rescues. The oldest is 4 and was neutered back at Christmas. The other is about a year and was neutered about 2 months ago. The oldest just lost his bonded male mate. Both are housed where they can nose each other. They are non aggressive when they can touch nose to nose, but fight when let loose together. They do not fight constantly. Do you think they will ever bond? With the youngest being just recently neutered, will I see less aggression over the next 6 months. Suggestions on trying to get them to bond would be appreciated. Thanks!
