I still cannot believe the price for what you get. I have researched many a cage for guinea pigs over the years and for a great starter setup it cannot be beat. This setup should be a standard setup in the pet stores at this price point. I have had guinea pigs for many years and purchased the jumbo for two, 3 year old female guinea pigs, to be used as a traveling cage when out in our RV. They already have a guinea pig mega palace in our house but with two needed something that met space requirements. I like the bar construction and silver color as I have a chewer so it should be less noticeable when she marks them up but the bottom is high so hopefully she will leave most of them alone. I plan to use the deck as the feeding center as the large opening on the top will allow easy access for cleaning and for getting their food bowls, pellets, hay etc. in and out. Also the large opening at the top means that taking them in and out of the cage will stop them from getting their back paws caught in the bars as happens with other cages and smaller openings. Daily cleaning should be a breeze as well. I use cotton towels covered by fleece on the bottom and the deck will gets pee pads covered by standard guinea pig bedding. I have already tested their ability to negotiate the ramp and as reported by other reviews it is the one downside as it is very slick and mature gps are quite hesitate to use it even though mine are familiar with ramps covered in felt in their usual cage. Smaller gps will probably get used to it but mature gps can be a bit stubborn when it comes to new things and routines.I did modify the ramp using a piece of coroplast purchased from the local home improvement store (color is limited but much cheaper than online) wrapped it in felt and secured on the underside with double-sided carpet tape. Drilling holes at the top and bottom ….this is secured to to the ramp by zipties and does not move. It makes it much better and more solid for them and their weight. I also modified the upper deck area by measuring and cutting out coroplast which is attached to the 3 sides of the cage around the deck so they feel comfortable and hidden while eating. GPs generally will not eat out in the open and I did not want them to eat under the deck because they do fight over food or their special eating space. If they are being watched the dominant one will behave. This will also keep the bedding, their feces, hay etc. in the cage and not spilling thru the bars. This was also attached by using zipties. Finally I cut a piece of coroplast for the top over the deck again in the interest of their well being and being hidden while eating. In the future I plan to get a piece of cloudy Lexan for the top to make it brighter but had extra coroplast to use up. This was secured under the bars of the top again using zipties. Now I have a very functional deck which makes it easier for me to feed them, watch them and clean. I do not use hayracks as the gps just pull all the hay down and then burrow into it. If I did I would have had to cut one side of the coroplast shorter to allow for the hayrack and water bottle. I attached pictures of my modifications. Even with some modifications ...this cage is a deal!
