There are a variety of sound samples available inexpensively online through SoundBible and SoundBoard, both of which have at least one short clip of a bobcat. SoundBible clips are free of charge. SoundBoard charges a small fee for use of their clips.
When trying to locate a sound clip, it is first necessary to have an idea of how you want to use it. Many local and national zoos have sound clips of animals in their collections, but downloads are not commonly available. Both SoundBoard and SoundBible have a variety of sound clips available for download in multiple formats. Before using bobcat soundclips found online, make sure you have permission to do so for your creative or commercial purposes.
