looks pretty darn good for your first build...good job!!! my first cage was awful..hehe..
u might wanna be careful with the large holed pieces along the top..i see u covered one of the big ones up on the bottom thats good...but all my buns found the larger holed cubes up top like that and kept jamming their heads thru and trying to squeeze out of there..and i dont have little buns ..i use the big hole cubes for the top of the cage cuz they cant get all the way up there very easy...its frustrating to be building ur cage and find that not all the pieces are the same size...grrr.
for my flemmies i go one more row up and i give them a whole shelf in the back..they love it ....i have to have tops on all my cages cuz i have pitbulls and i dont give them any opportunity to meet face to face..
good job on ur cage ..ur gonna find it kinda fun to add onto it..i have all kinds of ideas for NIC cages ,.,i have 10 bunnies and weve built and tore down and rebuilt all of them numerous times just to get them right for each bunnies personality.....we buy zipties in bulk,,hehe.not sure if u want to do a shelf or if u have a door for them or not..what ideas do you have for the rest of it.?
