In Jain tradition, Neminath Bhagwan did not approve of violence or non-veg.

What happened at the wedding was this:

• The wedding arrangements included a meat feast for many guests.
• Animals had been gathered for slaughter.
• When Neminath Bhagwan heard the cries and saw the cruelty, his compassion awakened.
• He immediately renounced marriage and worldly life and went toward diksha.

So the meaning of the story is:

• It was not because Neminath Bhagwan wanted non-veg.
• It shows that even in a royal wedding, ahimsa is supreme.
• His renunciation teaches that a true soul cannot accept violence.

In Jain Dharma, this episode is remembered to show:

• the cruelty of animal killing,
• the greatness of compassion,
• and the turning away from worldly attachments.

So the answer is: animals were kept for feast as part of the wedding arrangement, but Neminath Bhagwan rejected that violence and left the wedding.
