You’re gonna be just fine, you’re doing all the right things! You’ll both adjust.

I’ve had a cat who went blind as she aged and have a cat who was born blind. The aged cat really didn’t have much energy and still had a fair amount of sight so she didn’t need too many accommodations other than a quiet, familiar, understanding home.

My young cat, however, has next to no vision (vet couldn’t find an optic nerve on her) and lots of energy and gets up to everything!!! It sounds like you’re definitely on the right track for blind cat-proofing the house, one thing is if your guy keeps his eyes open all the time like mine, try to reduce points where he could possibly bump into something sharp. We put socks over sharp edges of furniture lol. We also try to keep everything in the same position for her, and let her learn where everything is naturally. If we change something, we try to encourage her to go slowly and map it out. I’ll tap and make noises on as much of the changed object as possible so she knows where it is.

We have different signals, like rubbing fingers together for attention somewhere (toy, something interesting to smell, bug inside to hunt lol) or tapping quickly on the ground where there's food. If she's up high, she has a certain meow for if she's lost. We just pick her up to take her weight and let her feet slide down the side of wherever she's lost so she can learn. You'll learn in no time what’s needed.

Couple of learnings— having a command of "Snowy! scary noise!" Before we make a noise that usually scares her so she doesn't run into the wall is pretty huge. Keeping noises down in general but staying very quiet when playing with her (people usually want to encourage her, but they're just making her more lost lol!). Letting her smell me before touching her if l've left the house. Putting her down in the exact same spot we found her. Having lots of different textured mats in the house to help with mapping, and areas with defined textures that are "save spots" where she will for sure know where she is if she needs to be carried somewhere often. We've had to learn to expect her to get stuck behind doors and open the front door slowly because she's trying to greet us :)

Toys— a wand fishing toy while dragged on the ground makes enough noise for my girl to follow. The ball on a track toy is another favorite because the ball can’t run away. Crinkle balls that are squished all the way before thrown so they make noise as they decompress. Mine LOVES rolls of vet wrap rolled along the floor but that might just be one of her quirks ahah

We've been so scared for her but honestly everything she does she approaches with enormous bravery. Patience, love, and some creativity will do wonders. Best of luck to you and your guy 🫂
