I save my cat when he was almost the same age as yours. Me and my wife took tremendous measures, having his best interests at heart.

For neutering, best determine the gender first.
If male, then the need is a tad lesser. Ours is not neutered yet too.

We fed our boy milk replacement on his 2nd month age, then starting 3rd month we gave him wet food.
Later on we slowly mix, and gradually kncrease the amount of kibbles and reducing wet food as time goes on. The process took about 2 or 3 weeks.

Now the guys 6.5kg
Before:


After:

A little, I think it's because it's not licking it's fur yet. My cat didn't start licking himself until he's older. So my wife would wipe him before we leave home for work and once we reach home. One day we found out, oh, the guy knows how to settle himself. Then we stop wiping him.

But as for wet food, you don't leave it. Because it goes bad later. Just feed it the portion as suggested, and don't leave food free flow. It is actually a bad habit and might pose difficulties in case you need to control it's food intake as part of weight management measures in the future. We only feed our boy once in morning and once in night. Even so, he managed to grow from 500 grams to the 6.5kg hulk of flesh/fat now.

If you really need to leave some food. Leave only dry kibbles as the state of the food doesn't detiorate that easily compared to wet food.

We humans might not be able to smell and determine that well, but cats being more sensitive, are extremely finicky when it comes to food and water. Hence wet food which deteriorates quickly, will keep the cat away from food. Dry food however, is like crackers to them. So they will eat it as long as its not exposed more than a day.
Water is the same too. You might have to change water twice a day or so. At least my cat, in his case.

Hence the storage of your kibbles is important too.
I once had a box of kibbles whicj was left open for a day, we've forgotten and left the lid open. That box was left unfinished as my cat wouldn't eat it anymore. It knows whether the food is fresh, or not. That box of kibbles was then "donated" to my wife's mother who leaves the occasional food bowl behind her house for stray cats, which help keeps off mice.

Normally this is what my wife does, she buys a big bag of kibbles, normally 1.6kg I think. Then she will pour a portion of it, maybe one-fifth of it into a container. And the rest is sealed in the original packing, since most pet food packaging has sealing strip nowadays. So we would normally dispense food for our cat from that container. And we will replenish the container as needed. So by doing this we reduce the exposure of food and preserve it's freshness.
And we normally use pine wood litter, as opposed to clay and silicone. Less health risk and easier to dispose.

Not expensive, I forgot the price. It's cheaper than silica and more or less same price range as clay. But clay clutters your toilet pipes if you flush them down, and as times goes, more and more will accumulate.

But wood is easier to dispose of. Silica is the best, but the silica dust is bad for health, us and cats alike. And it's so small, my cat almost have to sit for an operation to remove a silica flake caught in his nostrils. That's why we changed to pine wood.

Be wary of the weight too. Too light, your cat might accidentally topple tthe pan, and frighten itself. Then you can never use that type of litter again. My previous cat toppled pine wood, and whenever she smell and know it's pine wood, she will not use that litter, and will pester my wife to change.

OK. But if pine wood don't pour too much. Enough weight will suffice. Too much is wasteful

I have not seen tofu litter before.
Recycled paper one is the best actually. But too light for my cat. He will topple the whole pan and frighten himself.

Pine wood doesn't clutter. The only downside is that if your cat urines a lot, the pine wood pallets will easily be reduced to wooden saw dust. And at this state, it will slowly loose the ability to eliminate smell, especially if your cat urines a lot.
