I think 'Avatar: The Last Airbender' has some cool animal designs that could be seen as having a certain appeal. However, it's not exactly what you'd call 'sexy'. Maybe you should look for specific anime or indie works for more explicit examples.
One popular example could be 'Zootopia' which features various animals in a modern city setting, although it might not be considered strictly 'sexy'.
Well, 'The Lion King' is known worldwide and has some attractive animal characters, but again, not really in a sexy way. But there are some indie cartoons that might fit the bill, like certain adult-oriented web comics that focus on more sensual depictions of animals, but they're not mainstream.
