Hello! I can see what you are making here has the beginnings of a really good race, but I can't help but notice a couple of problems with this race. Rather than be negative about it, I am going to point out the problems I found, and also suggest ways to improve on them. You don't have to take my advice, of course, but I feel like this race does need a few little tweaks. For this, I will be splitting my suggestions into two sub groups: Additions and Changes.

[Additions]

1. Ability Score Increase. All races need to boost stats in some way. This allows them to suit certain classes really well, or just help tie in the backstory to the race. Most "Single races" (a term I use for races without any sub races) increase one stat by 2 points, and another stat by 1 point. This race seems like a stealthy, cunning one, perfect for a rogue, so I would say "+2 to Dexterity, +1 to Intelligence".
2. Age/Alignment tabs. I have put these two together because they serve towards the same purpose: racial background. An age tab should tell you when a member of the race is considered "of age", as well as how long they live for. This doesn't seem that important at first, but how long a race lives may impact how they live their lives. Humans strive to make themselves memorable, so they may out live their short lifespans in the history books, whereas elves can afford to take their time in life, experiencing all its pleasures over the course of up to 800 years. Alignment tells a player the kind of standards a community lives by. A lawful racial trend may mean that they stay loyal to their community, whereas chaotic can mean they often live among other societies causing trouble.
3. Size. A size tab should tell you the race's average height or height range, weight range and size category. While this is mostly for RP purposes, height can effect gameplay, and your size category always will. As for this race, I would say it is medium, and this assumption will be used later.
4. Speed. This section tells you how far you can move in one round of combat. As a base, most medium races have a walking speed of 30 feet, whereas small races have 25 feet of movement. You could apply the Tabaxi's temporary speed boost trait, but that isn't necessary.
5. Languages. As written, this race cannot speak, read or understand any languages. You should add at least Common, so a player can talk to most other PC's (Player Characters), and then allowing the player to choose one other language of their choice.

[Changes]

1. Cats Claws. This feature does not make sense to me, as it doesn't say what you can use your claws for. Consider changing it to be "Your unarmed strikes deal 1d4 (piercing or slashing) damage".
2. Keen Smell. As they are night hunters, I would change this feature to either the elf's "Keen Senses" (Perception proficiency) or the Tabaxi's "Cat's Talent" (Stealth and Perception proficiencies) feature.
3. Acidic Blood. Without further background knowledge, this trait seems out of place to me. Still, I have tried my best to make a suggestion on how to improve it a little, so here is a version of the trait I wrote up.
   Acidic Blood: As a bonus action, you can coat a blade or arrow with your blood, which contains a weak poison. If you do so, you take one point of piercing damage, but your next attack made with that weapon within the next minute deals an extra 1d4 poison damage.

I hope these suggestions will be of use to you. Just remember that this is only my opinion, and you can do whatever you want with your work.
