What would you say to keeping Ferrets? they have to eat meat sadley, they dont eat veggeis or fruit, Murphy was a rescue and i dont think i can rehome him after all the trumer he has been through unless it was to a experianced ferret handler.
I have pro"s an con's about animals in cages.
pro's~if the cages are big, safe and full of stuff to keep the animals entertained i think they are alright. For example : i have 6 female rabbits living in a pen together, i would prefer them to be outside on the grass but with foxes, hawks and dogs around it is not a safe option to have them out running around all day. There pen is 10m x 15m big, wich gives them plenty of room to run around and play. They also have natural logs and hollows to hide in, Wood Blocks to climb, hammocks and dirt piles they can dig burrows in. They get feed twice a day, there main meal includes: wild grasses, roots, corn, barley, lucent ( green and white ) pellets, nuts and scraps ( lettuce, carrot, watermelon, marnderines ect ). I grow most of there food to save on feed costs. I take them out for runs on the grass with there harness on and they love it.
My rat Napoleaon lives in a 3 story cage, hammocks, logs, climbing ropes, stairs, hay, sawdust are only some of the instruments to keep him entertained through out the day since his partner in crime sadley passed away 2 weeks ago, i get him out and play wiith him and he loves it

I think if you do these kind of things its oki to have companion animals ~ also only if you rescue them

Con"s ~ Small, dirty, Cramped, diseased and overall descusting cages are NOT acceptable. If anybody keeps animals in these areas with not stimulation they shouldnt have animals . simple.
Some animals prefer human attention over there same species. A good example is Chester one of my sheep. He lives with 2 ewe's ( female sheep ) and a pig, yet he will always choose human affection over the 2 sheep and pig. He will do anything to empress you and get your attention. I think if he had his way he would sleep inside the house with us over the sheep and piggy.
sorry for the long post

just wanted to say my opinion on cages
