...California Desert Tortoise's...they are SMARTER than they look...
We had one, decades ago, when they were actually sold in pet stores. They are a State Reptile, now, so they are protected.
My H and I were living in the Fresno area, it actually is very close to being a desert. I bought a large desert tortoise, it was about 10" across. It was male, and I named it 'Tommy'. My mother had grown up in SW Texas, and was surprised to see the reptile in our back yard. We had very sturdy fences, and I would check them every day, looking for signs of digging, and fill in any I found and place large rocks over the area. She wouldn't call him "Tommy", she called him "Mr T". (LOL...I should SUE the actor...he probably overheard us talking about Mr T...and decided to STEAL the name!!!!

)
We had a mulberry tree in the yard, and Mr T liked how they tasted. So, when me, or the kids would go into the back yard, Mr T would walk to the tree, and look at us. We would walk over to where he was, and pull down some leaves and set them in front of him, and he would eat them. My mother was visiting, and she walked onto the back porch, to get some air...(To smoke a cigarette...I made it clear that she couldn't smoke in my house...I have asthma, and am allergic to such smoke...probably why my mental development was crippled...I SHOULD have had a LOT MORE LETTERS AFTER MY NAME!!! (Just joking)) Anyway...
I walked out, and my mother asked, "Why is Mr T looking at me?" I looked over, and Mr T was under the tree, looking at us. I said, "He wants some leaves, go pick a couple for him." She did, and was astonished that he began eating them. "That turtle is a begger" she claimed. I just laughed, I had tried to explain to her that Mr T was a tortoise, but to her, ALL creatures with large shells were 'turtles'. I just agreed...but he could also ISSUE ORDERS!!!

We would bring him in during the winter, it was too cold and wet to leave him outside. We just let him loose in the house, but kept most doors closed, we didn't want to have to hunt him down, and find him in a place that we didn't want him to be in. He wasn't very messy, and it was fun to sit and watch as he walked. We kept the back patio doors uncovered, so he could sit and get sunlight. He quickly learned the layout. We had a flat dish where we would put lettuce and other vegetables so he could eat, in the kitchen, and a shallow bowl of water. BTW...tortoises can hold a LOT of water. He wouldn't drink very often, but when he did, he would almost DRAIN the bowl. I would watch, and marvel, and wonder how he was holding so much water in his body. He soon learned where the food would be set out...and...
...WHERE IT WAS KEPT!!!!
I would be reading a book in the living room, and he would walk over, and BITE MY TOES!!! Tortoises don't have teeth, so it didn't hurt. I would look down, and he would amble over to the fridge, look at it, and look back at me. I figure that he was saying...
...HEY HUMAN...I CAN'T TALK...BUT...I AM HUNGRY!!!!

FEED ME!!!
I would get up, apologize, and go over, open the fridge, get out lettuce, and add other vegetables, and make him a nice meal, and set it in the dish. He would walk over, and eat.
...

...He was stolen from us.
...We all searched for him one morning, and couldn't find him, and there were no signs of digging..
We figured that word had gotten around, and so some kids probably decided to steal him.
At that time, I REALLY WISHED that I wasn't allergic to dogs. It would have been nice to have an Alsatian in the back yard. Although, once my brother brought his over to visit, it walked around, sniffing, found Mr T...and...
...PEED ON HIM!!!

...I got the dog away, and washed Mr T down.
Pets have interesting challenges, and it is fun to watch them.
