This will probably sound daft but oh well...I have got two 6 month old kittens, they are desperate to go outside but I won't let them yet (not long been neutered, fur still growing back, & need micro-chipping after Christmas)
Anyway, when I do let them out are they likely to stay together or just leave each other and do what ever they like out there 
Anyone with 2 (or more) cats, do you know what they are like outside??
In the house they are basically stuck together most of the time
