In your opinion, are singles OK to keep? I keep reading about pairs. Or is it like rabbits, where generally 2 is better, but singles are ok too.
He's leaning more toward rats. Do you think the heat will be an issue. I'm wondering if we'll just have to keep a wet rag over the cage, maybe, to help keep it cool?
IMO the rats will be like rabbits in the heat. If you can keep your rabbits comfy in the heat, rats should be fine.
Honestly when it comes to heat, its harder for animals to go from really cool to really hot then it is for them to stay at a consistent temp. Up here in the nasty North West, we go from about 60f in the house in the winter to 90f + in the summer in the house (NO AC when it hits 110 outside and bakes us in the house). It was raining this AM and pretty cloudy and in the last hour or so its just starting to become sunny and inside the house is sitting at 78 right now. So during the summer, were MUCH warmer inside and the rats could care less. Never had an issue with heat with any of my animals except myself!
As per singles/doubles. Doubles are definetly better, and it doesn't affect how social they are, just the size of cage you get. Its really cute to see them snuggle with each other.
I kept my group of 4 girls (down to 3 now) in this cage (not my ad)
http://vancouver.en.craigslist.ca/rds/for/3972359196.html its 27"x23"x33"h not including the legs. I have it decked out with laminate flooring as shelves, flexible drainage tubes for tunnels, hammocks, solid ladders, etc.I have a dog bed under the cage so its not wasted space.
I also have a single female rat. She was a few months old when I got a second rat, and she wanted NOTHING to do with this new friend! She would actually draw blood on this new rat. So I ended up getting the new rat a friend right away, and leaving the single rat single. My single rat is my friendliest, but I also took her home when she was about 1.5 - 2wks old (GRAPHIC NOTE - I had a snake that refused to eat and it was my last ditch attempt before tube feeding this snake... Needless to say the snake hid under the rat, and the rat fell asleep on top of the snake.)
So honestly, my single girl is totally fine on her own, but she never had the opportunity to grow up with other rats, she came to me when her eyes were barley open so she didn't get to grow up with her litter or other rats. I think if she did, she might be a little more upset and anti social with out a friend. She grew up knowing HEY! you fed me! you're my mommy!
I think a single is doable, given a lot of social time, but honestly, its easier to keep 2 rats then it is 2 rabbits. They don't need as much extra room in comparison for a 2nd buddy.
So long story short, I would personally go for 2. When I get more rats after I loose my current girls, I will always get them in pairs. As for the heat, I would just offer a ceramic tile or marble slab if you're worried. Little fan in the room for a gentle breeze to keep air moving might help too, but honestly I'm a wuss in the heat (and the cold...) but our animals do fine.
