Congrats on the new cridders
Mine travel pretty well, But keep in mind, no 2 are the same. Being prepared is the best way to make traveling for gliders less stressful. One duffle bag of stuff for you for a weekend won't be the case anymore lol. It's like packing for 2 small toddlers!!
Here's a few things to consider to make it easier. Gliders travel pretty well in a bonding pouch during the day. So if you drive there and back during the day it's not so bad. However, if you'r drive time is at night they are NOT happy confined in a pouch!! You will need a travel cage for your vehicle.
Ex; We left to come home from Tampa around 7pm for an hour they were fine in the pouch, once it got dark we had to pull over and put them in the cage. The cage has the seat belt wrapped around it and buckled. Wake up time is also feeding time so we made sure we had food handy for them in a cooler.
If we are going to be anywhere longer than a day or two we bring their regular cage. Small cages for too long can stress them out, especially when they are used to bigger cages. If this is going to be a regular trip for them ( twice a month ) Consider getting a second cage to leave at your girlfriends.
Having things that are theirs and smell like "home" like toys, fleece, pouches etc also helps relieve their stress when traveling. You can also borrow your girlfriends tshirt to put on top of their cage at home. It will get them familiar with her scent before they even meet her.
Small cages are fine in the car but they do need lots of space in their cage. It's much easier to have a second cage rather than loading and unloading possibly causing damage to their normal cage.
Bring toys, and enough staple food for your stay, can always pick up fruits n vegs once your there.
If the girlfriend has pets make sure the gliders have a safe room that her pet/pets don't have access to.
Make sure you have a safe wheel! one that can be easily removed from one cage to put in the other. We have a large wheel for the cage and a small wheel for the travel cage. And they do use it in the car lol
Last but not in any way least, find a vet experienced with gliders in the are your girlfriend lives in case of emergencies.
Your new cridders are both male, you will seriously want to consider having them both neutered! These are very territorial animals and as they mature they will become aggressive with each other and possibly fight for "top glider".
Intact males also smell!! a very strong pungent smell! They will mark everything insight including YOU. Once they have been neutered the scent gland dries up and they don't smell nearly as bad. Hormone levels also reduce so there is less posturing for the dominant position (lessens aggressiveness and fighting )
I'm sure I have forgotten something as I haven't had coffee yet lol but anyway good luck to ya and the new babies
