Thought Provoking Post #002 - Zootopia - Interspecies Relationships

Another Thought Provoking Post,
This is the first out of the few Zootopia related post I am planning to post,
Though there will be now Zootopia review on the site as the movie already has very good reviews and rightfully so.

So lets begin with the Thought Provoking Post (NO SPOILERS)

Interspecies Relationship

In a world where there were no humans, And animals were to take our place as civilized sentient beings able to communicate between each other. Where Predators no longer hunt and Prey no longer cower in fear, It is a more peaceful time.

As you watch the movie you will still notice that the number of visible interspecies relationships are very minimal. This could be the movies way of poking at the fact that most people are more comfortable hanging out or being friends with those of the same race.

So in terms of friendships there is still some diversity though very minimal, Another noticeable separation is between the Predators and Preys.

On the other hand in terms of a more intimate relationship between lovers, There does not seem to be any to be seen throughout the movie.

So more in depth on this, In terms of the survivability of a species there would be problems if animals were to procreate with other species since most interspecies young are sterile and unable to create the next generation of young. (Other than the Tigons and Ligers).
But in comparison to the time when they were all wild, The Animals now live in a more peaceful time where species can live in harmony (being able to function as a civilized  society together).

A Civilized time where child mortality rate would have surely been dropped to an all time low for any and all species (Our Protagonists has 275 Siblings). You would think that procreation would be a minor thing in mind when looking for an intimate partner.

So what are you thoughts on this?
The city of Zootropolis is no new city,
But could the past have traumatized these animals and though they live in such peaceful times there is still traces of Speciesism in them all?
Could Interspecies Relationships still be an undiscovered thing?
Could Gazelle and one of her backup dancers be the first  Interspecies Celebrity Couple?
