I used to have an "Extra large" pet store cage. I could never fit toy in it only food and 1 pigloo (this was for 2 piggies. It was 3 ft. I think. So I decided C&C. I buult a 2 by 4 C&C cage. My piggies were cautious at first but then started popcirning everywhere and eat there hay and exploring and testing all the toys they never had. Luckily I only had them in the small cage for 1 month. IT WAS $75! I did tho keep it for travel and hospital uses....I put a little bridge for them to climb and I made a little cupcake house. Tunnels and stuff. They soon found where I placed the veggies and.fruits....lets just say it got loud. I will post pictures soon. Just wanted to share that they are now happy and nit cramped.
