You can use that stuff, just be careful that it gets changed immediately when soiled on. Could harbor some nasty bacteria if it stays wet and nasty for too long. 
On handling mackies....most are territorial from what I've found. The female I rescued a couple years back was VERY territorial. In fact, that's the reason no one at the store fed her, gave her water OR cleaned out the four piles of poop/urates in her tank! When I first met her, I let her come to me because I got this look from her and a haunting feeling that I should remove my hand when I first attempted the idea of sticking my hand in there. If I let her come to me (which they are very curious and always seem to want out after they get their first taste of adventures in the house, LOL) she was a gentle, perfect lady. After realizing I was the only one that gave her fresh water on my once a week trips, I took her home. She only popped me once, and that was for sticking my hand IN the bag to get her out once home rather than using a hook. Using a hook meant to her that I was not invading her turf but I was going to let her come out for exploring time.
My baby rotis are NOT aggressive at all. Granted, I try not to teach my animals I can stick my hand in their turf and get them out (although, my rainbow boa and my Nyoka have always been taken out by hand since neonatehood) except for the one female who is afraid of the hook. I will see tomorrow upon my first handling session with her if she reacts like her brother and sister and just calmly explores everything. I don't perceive her being an aggressive animal though.
Most mackies as babies pop anything that moves (huh, kinda like my scrubs. LOL!) but I think that's more related to the HUGE feeding response these guys have. Some people call them their garbage cans because they never turn down a free meal. ;D
My little male is the first one after he had his first meal two weeks ago to always greet me in the mornings when I wake up seeing if I'm going to give him some food. hehe
I don't like how most people label baby macks as "aggressive" Far from the truth, they LOVE to eat and once you get them started, they never want to stop. That coupled with what looks like being territorial like retics usually get, is the only reason apparently why they will strike repeatedly. Heck, if I lived only in a small section of my wilderness and some jerk kept sticking their grubby paw in my world uninvited, I might have to bite them to just to get them away. I feel that's their home, their safety zone so no touchy. ;D
Is this your first macklott? Sorry for the long post...got me on a chatty evening. LOL!
Hugs!
