As an 'artist' I think it is best to have your own reference material. So a friend of mine told me that participating in free photo shoots could be a good option to gather pictures of lovely animals. The idea is that the 'models' and photographers come together, both for free. Afterwards, all the 'models' receive some pictures (web format) of the shoot.
My first shoot was at a wonderful flowering moorland, and there were 12 lovely models. So sit back and relax and watch the slide show of the results.
