Our Cat is called Millie. She sleeps on our heads and knocks on the door or window with her paw when she wants to come in. She's purry and friendly most of the time - but she will scratch your whole arm off if you stroke her the wrong way. Dog's I don't know about - never had one - they seem to be more fun. They have happy waggy tails (whereas a cat's swishey tail means someone is about to catch it) and they bounce around the place. You can take a dog for a walk and they will bring back a stick -which is cool. If i threw a stick for Millie she'd tell me to get it myself.
Remember Taking good pics of your pets is usually about having your camera close by. They do strange random stuff and you need to be ready to catch it when it happens. That's why phone cameras are great for general pet snaps. You might decide to take an action picture of your pet (but probably not if it's a tortoise ) or find a nice spot to take a portrait.
The single most important piece of advice for shooting pet pictures is to get down to the same level. Look at the images in these galleries - almost all are shot from ground level. Eye level is key for portrait photographers and the same thing applies to pet photography.
In the house and around the garden
Out and About Running and jumping dogs need 1. Fast Shutter Speed (1/500th sec and up) 2. AI or Servo autofocus - which means the focus will follow a moving subject and keep it sharp 3. Continuous motordrive Set these yourself if you have a Dslr or Bridge camera or let the wizardry of modern cameras take over and choose Sport Mode
Phone users can try burst mode by keeping a finger on the shoot button
