Non-Clan Cats

Cats that don't live in the clans often are clumped together by the clan cats, though reach specific kind tends to be treated a certain ways. 

Clan views:

Thicketclan:

General: Thicketclan usually finds a fair amount of non-clan cats on their borders, some types more than others. Out of all the clans, Thicketclan is the one most likely to take in a non-clan cat into their numbers.

Rogues

Cautiously approached. Thicketclan isn't a clan for outright fights. More often than not, they'll observe a rogue from the shadows to see if there's even a chance of them being suitable for the clan's life. More often than not though, they'll scare the rogue off from the shadows or, if the rogue is persistent in some cases, ambush them to get them to leave.

Loners

A fair amount of Thicketclan's numbers come from bloodlines where they invited a loner or two in. It's not an immediate invitation though. Usually, they'll wait for a moon or two to observe the loner, both from the shadows and in face-to-face meetings to see if the cat is suitable for their way of life. If the loner passes this time period, they'll be given the chance to join the clan.

Kittypets

Kittypets are a rarity for the clan to come across. Those that often come across the border are ones more often than not completely lost. Thicketclan looks down on these cats, but won't leave them be either. They'll escort whatever poor kittypet came across them to The Hollow and then direct them to Creekclan, who are usually more suited to help the lost feline. These cats may be given the opportunity to join, but it's less likely than a rogue being invited into the clan.

Gorgeclan:

General: Gorgeclan, given its terrain, doesn't come across many non-clan cats. They're friendly if one comes across one of their patrols, but their isolation thanks to the cliffs and gorge that is their home make some communication difficulties.

Rogues

The clan is willing to reason and see if any rogue lucky (or unlucky) enough to come across them would like to join. Those nice enough to not attack but also not want to join are escorted back out of the territory. Those that are outright hostile don't tend to have the luck of getting back out of the gorge. Gorgeclan cats tend to be nice, not pushovers.

Loners

Same as rogues, though arguably more welcoming. Loners don't tend to be hostile in the same ways as rogues. 

Kittypets

Same as loners, added with the expression of "How the hell did you get here?!" Gorgeclan might as well be the clan that finding or coming across a kittypet of all cats is near impossible.

Sunclan:

General: Sunclan has the reputation of trying to fight everyone, so it should be no surprise that they're far from the friendliest clan to any non-clan cat. 

Rogues

Fight them, claw them, drive them away. That is Sunclan's attitude towards rogues. These cats are the ones that the clan fights the most. 

Loners

Sunclan still fights them, though surprisingly has invited one or two in the past to join the clan. The reason why though has been lost to time. And maybe denial. 

Kittypets

Sunclan actually has a similar attitude to kittypets as Thicketclan, including the rarity of any kittypet coming across their territory. There is often a heavy 'tough love' to them trying to get the lost kittypet to where they need to go to get the more appropriate help. 

Creekclan:

General: By far the friendliest clan most non-clan cats could meet. Both for better and for worst. For the clan or for the non-clan cats can be up to their own debate.

Rogues

Creekclan has very much openly invited rogues to join in the past if said rogue didn't attack them outright. Those that do seem at first to get a good advantage... and then suddenly get overswarmed in numbers as other warriors from the clan hone in on the attack in waves. And if the said rogue is able to live... they better not come around again or else that ass becomes grass.

Loners

Creekclan is unbelievably welcoming towards loners, even more so than they are towards rogues. And any who reject the offer (which has been quite a lot) are still welcome to visit. 

Kittypets

Creekclan will take in any lost kittypet as their own up til they are done helping them return home, and those that join are treated as if they are family. This clan is the one clan has that the most interactions with kittypets and a good number of the clan's cats have kittypet ancestors when compared to the other clans. Add in that Sunclan and Thicketclan will direct any kittypets they come across to Creekclan, it's no wonder how Creekclan keeps up its "soft" appearance.

Floodclan:

General: Floodclan rarely has interactions with non-clan cats due to the flooding their territory gets in new-leaf and green-leaf. This clan is also the only clan that sees non-clan blood in their own numbers as 'disappointing' at best, especially since they cheer when one of their warriors are found out to have been involved and produced offspring with warriors from the other clans. Those that do trespass though...

Rogues

Floodclan will chase any rogue out, no questions about it. They despise any and all rogues they come across and if they find out one of the other clans (more often than not Creekclan) has taken in a rogue, they would spit upon such a fact. Those in the clan that are found out to have had relations with a rogue are also looked down upon. 

Loners

They might not be chased out immediately, but that does not make Floodclan any friendlier. The best any loner can hope to get from Floodclan is to be escorted back out of the territory. Those in the clan that is found out to have loner blood aren't treated much any different from the average warrior, aside from the usual comment of the matter being 'disappointing.'

Kittypets

Other clans might take pity on kittypets, but Floodclan has been known to mock them. To Floodclan, they are the softest, most pathetic sort of cats to exist. If someone in Floodclan is found out to have kittypet blood, no matter how far back in the lineage it may be, one could expect to be mocked just as much.
