okay yes shane wouldn't like dogs sorry i really think he wouldn't enjoy a dog he thinks they're gross (he doesn't mind being one though). but! shane and ilya would have a cat after retiring and! shane grew up with a little kitty cat.
yuna and david got her after realizing they really couldn't have anymore kids and felt bad about shane being an only child (i like to think yuna has a younger sister somewhere and david grew up with a lot of family close by), so when shane was seven years old, they got him a cutie little white and ginger kitty and named her cinnamon, cinny for short, because shane isn't creative with names.
actually, i think shane's parents did that thing where they have the kid do research and prove that they know how to take care of the pet before getting it, and shane is allll in because he 1) likes a challenge and being good and smart and 2) because he really does like cats, maybe one of his teammates has one and he was influenced.
he looooves that cat. so much. shane thinks she's so adorable as a baby and as she grows up, she's just this sweet, soft animal that shane is always happy to come home to. cinny always knows when he needs comfort and shane's cried straight into her fur tons of times. when they first got her, yuna and david put a ban on animals in the bed, but they relaxed once she was a year old and shane asked so nicely with his good boy eyes sparkling and one tooth missing if cinny could pleaseee stay in bed with him tonight, pleaseee mom and dad! of course, they relented and they shared a bed forevermore.
cinny is less the hollanders cat and moreso shane's cat. he's the one that feeds her, plays with her, buys her toys with his allowance money, cleans the litter box, etc. she loves shane the most, because they're pack bonded and he lets her do what she wants, but she also likes to cuddle up with david when he comes home from work and he's relaxing on the couch. cinny is ... okay with yuna. yuna cares about cinny, of course, but sometimes she gets in her way and yuna gets frustrated that she can't communicate directly with cinny. also i think she's just a bit too rough with animals, has been since she was a kid and was a local terror on the petting zoo, so cinny never heads to her lap first.
shane never ever lets her out of the house on her own, he saw one dead cat in the road when he was eight and decided to never let cinny out of the house if she isn't in his arms. he liked to show her the garden in the spring and summer and would set her down in the trampoline so she could enjoy some sunshine.
he was always so sad when he had to be out of the house for hockey games and it always took a little longer to fall asleep those nights. yuna has a video stored somewhere of shane coming back for christmas from his first season billeting. he opens the door and cinny perks up, then walks over with a little mew. then she circles his foot once, twice, as shane puts his bags down, then she jumps up into his arms as shane hugs her. yuna ends the video after cooing over the two, but there's a second one from hours later into the night where shane is on the couch and talking to david while he's still holding cinny with her little head tucked in his neck. a third video, much shorter, is just a video slowly zooming in on shane and cinny in shane's bed, asleep and curled together.
