Why not check out one of the inexpensive stock photo sites (istockphoto, etc.) or wikimedia commons (all free - some are public domain, others require that if you use it you must attribute the image owner).
I just happen to have an 8MP camera and two full-grown Bengals, but if you want a photo of a normal cat they may not suit your needs... Google bengals to see what they look like. Ours have spots like mini-leopards.
i have a 12 mp camera with digital photo and video 30 fps capability.
Do you have custom requirements not typically found or accepted on istockphoto and microstock sites?
