The Jack Russell Terrier's I'm familiar are known for their hyperness. I agree with Wisewoman about mixes. My parents had a mixed Bijon/Maltese that was just precious. After it died they got a true Bijon. I get all my pets from the SPCA and always get animals that are 2-3 years old; that way the puppy/kitty has had time to mature!

During the times in the past I was at my worst and just wanted to stay in bed all day, knowing I had 3 animals at one time forced me to get up, feed them, let them out and do it again in the evening.

Even now, although one adult cat isn't hard to take care of...she follows me around like she is keeping "tabs" on me and if she thinks "we've" slept too long in the mornings, she sits on my end table and stares at me...lol.

I vote for a pet companion!
