Your cat!Jure ask made think and now I'm having so many Thoughts™ sooooo, imagine this:
Bojan is a doghuman (a golden retriever puppy if you may) the same way you said Jure was a cathuman. They both have some dog/cat features even in their human forms, but they can hide it really well unless there's some really strong emotions that make them pop up, and they can turn into their full animal form whenever they want.
Even if they're very good at hiding their animal features, it still takes a bit of energy and concentration to do so, so when it's just them and the boys (who are probably the only ones who know about it), they can finally fully relax and let their ears and tails pop up.
And you just can't tell me Bojan's tail wouldn't be wagging all the time from how happy he is. I can see they guys teasing him about it all the time, like when he gets mad for whatever reason and they apologize to him and give him so head scratches; he pretends to still be mad about it and he goes "you're not going to get me to forgive you just with some pets 😠" "you sure, pup? you're tail is wagging like crazy 😏" "oh shut UP"
(He also gets the zoomies from time to time of course agsjsbsj)
I think they would both LOVE turning into their animal forms to cuddle and take a little nap together. They all find it so funny that Bojan is somehow bigger than Jure when he's a dog, but despite the teasing, Jure loves getting to cuddle with him and it makes him feel so warm and safe. And he knows Bojan will always have his little 5pm nap, so cuddles will always be assured :3.
Whenever they meet up at Jan's, Jure will turn into a cat more than half the time to play with Igor and catch up with him. Igor tells him a lot of stuff - he's actually a really interesting cat, Janči - and then Jure can tell the guys what he said.
That's also why it took Igor a little more time warm up to Bojan because, even in his human form, he still smells like a dog (it's not perceptible to the human senses, but it is to the cat's), but he does eventually and they now all get along pretty well and he joins the cuddles during nap time sometimes 🥰.
I like to think Bojan was one of the first people to meet Pino when Nace brought him home and they immediately warmed up to each other. Sometimes Nace takes both of them on a walk so they can have some quality time together as well, and when they get back home Bojan returns to his human form and tells Nace all the good things Pino says about him – and Nace has probably cried a few times hearing just how much his beautiful puppy loves him 🥹💕
Also, they would definitely love going on little adventures with the band, going on a hike and being surrounded by nature so they can run around freely and have fun together (even more if Igor and Pino join them as well of course). The rest of the guys would have to keep an eye on them so they don't get lost or hurt themselves, but it's definitely worth it to see how much fun they have together <3
(wow you really got my mind going crazy omg 🫣)
