Despite your snottyness Lissa and Bellebelle I am going to have to say that the cage Bellebelle listed does seem to meet minimum size requirements, to a degree.
I looked over the site and measurements. Now it's hard to be certain that one of the measurements is for depth not height and if they are reversed it does not meet minimum size but I'm willing to give forth the benefit of the doubt and assume the longer length is for depth.
Taking into account the actual inside usable space and deducting some centemeters from the sites outside measurements that cage seems to meet the minimum size recommended and measures approx. 8 sq. feet or about 2' 4.5'. It still is NOT a 2x5 though so I was right in my deductions. It would be closer in size to a C&C 2x3
It is suitable for a single GP (which is never recommended) or 2 sows. 2 boars should not be housed in a cage that size though and certainly not 5 sows. So Ms. Lissa, you can stop acting so smug. Don't forget, that is Bellebelle's cage NOT yours where you house 5 sows. In fact your cage is smaller then Bellebelle's isn't it?
Now, on to other matters.
What kind of site do you people think you are on?
Did you all fail to notice that you are on a site called CavyCages? The title should give the site theme away. We are about getting away from small cages and making larger enclosures. If you state that you keep your animals in pet store cages you will be questioned. If you state you keep 5 sows in one pet store cage you will make people disgusted.
This is not one of those bubblegum forums where anything goes. There are no breeders/rescuers/petstore buyers coexisting in blissful communal apathy here. There will be no, "ohhh your guinea pigs are so cute, it's too bad the mother died giving birth, good luck next time". I DON'T THINK SO!
You are on a forum that takes a firm stance on animal welfare. We mods are not here to be your friends, or to even really keep the peace. We are here to keep this forum on track and to correct bad information. We were given the jobs because we are tough and unwaivering in our views. We are not here to coddle the kiddies that come here. If you are old enough to be using a computer and join a forum you are old enough to learn and take account for your words and actions.
When you join a forum with very strong views then feathers will get ruffled. Not everyone likes what we have to say. Especially the breeders, the hobbiests, the petstores and anyone that in not willing to accept that THEY CAN DO BETTER FOR THEIR PETS IF THEY ONLY CARED ENOUGH. There are plenty of members on this forum that started out the wrong way. I was one of them. My first GP was in a small cage for a little less then a month. I fed her crappy food, not enough hay and she had a salt wheel. I did my research, found C&C and realized I can do much better. The key though is that I cared enough to actually do better. I built a bigger cage and found my GP a friend.
Those of you who wish to leave can go. We aren't going to try to talk you into staying. You can go and find your cotton candy, bubblegum forum full of magical rainbows and unicorn guinea pigs. You will also find breeders, poor information and an unwillingness to stand up and really speak in a firm voice for the animals.
I'll be staying here where my voice is welcome and I can learn further how to end neglect and abuse with people of similar mind. Here with people willing to go beyond the rainbows and get in the mud to make a differance.
