DS wants a rat for his 10th birthday. As he has recently (the last year or so) got so much more responsible with helping out with the dogs and cat, we think he is probably ready for his own pet (supervised obviously)
As a child I also had rats but often had them singly. IIRC it was even recommended at one stage that you had a single to allow them to bond with you better, possibly introducing a second later on.
Now the advice seems firmly to be that rats should be kept in pairs or single sex groups. My single rats always spent a great deal of time out of the cage, not something that would be so easy here as we have dogs downstairs.
So should we go for a pair or would a single be ok?
