Dogs can guard and can be your friend, the same with Puppies but Cats, yuck. USA I was carrying in groceries one night and a moth flutterd in. It landed on the light. My cat sat down under the light looking like he was about to pounce. He caught it.
Snakes are kind of like a reptile.
They can be long or small. One of the largest snakes is the anaconda. It is very long and fat. One snake that is very deadly is the rattler. The only ways you know there is one by you without getting bitten is by hearing a rattle sound or sometimes you see it.
