Support animals

Is it possible to make it work with animal faces. Especially cats?

The library is for human face alignment. Research would start by reading the model architecture and training data in the repository to understand if the models can generalize to animal faces. Check the existing datasets and see if retraining or fine-tuning on animal face data is needed. 'Done' would be a model or demonstration that works on cat faces.
