Nibbles

Nibbles is a stray cat living in Megabuilding H10 who can potentially become V's pet in.

Background
Real animals in Night City are more than a rarity to behold, and while cats were said to be the last ones to disappear, it is still possible to encounter them in a precious few locations. As of 2077, the Night City Environmental Task Force have been using stray cats to address the rat plague in Watson. Where these animals can be found, as was the case with Nibbles, it is clear that they are taken care of by the city citizens, at least in terms of primary needs, although it does appear that they remain unowned due to the absurdly extortionate pet tax.

At some point in 2077, V found a bowl in a corridor of Megabuilding H10 alongside a shard. If they decided to leave some food in it, upon returning after a while, Johnny Silverhand appeared and made a comment after observing a cat eating from it. V was then able to interact with the animal, named Nibbles, and took it to their apartment, where Johnny and V observed it hanging out in a laundry basket. From that point on, Nibbles remained a permanent resident in V's home.

Nibbles seems to have a delicate palate, as the aforementioned shard states that she only eats a prescript cat food made of tofu and tuna. To prepare it, one has to mash it up a bit and then put it in the microwave for exactly 17.5 seconds. If Nibbles refuses to eat it, then a little splash of NiCola should do the trick. Although too much of the beverage can made her barf it right back up.

Nibbles as a companion remains in V's apartment at all times, where food, drink and a litterbox are provided, with no need of further maintenance. She will meow for attention and change positions occasionally. Nibbles may also interact with the iguana pet from time to time.

Acquisition
In order to obtain Nibbles as a pet, first you need to obtain Cat Food. You can find it in food stores or randomly in some places of Night City, like the the Arasaka Industrial Park or the Aldecaldos camp.

After completing Playing for Time at the start of Act 2, some time later the opportunity to adopt Nibbles will become available. You only need to venture left upon exiting V's apartment, follow the corridor and then turn right. In a trash bin just around the corner a shard titled "feed teh cat" can be found, while right below it will be an empty bowl. Interact with the bowl and fill it with cat food. Leave the megabuilding and return some time later.

After a while, upon returning to the bowl, the a cat will be eating from it. If V interacts with Nibbles, they will be given the option to "pick up" the cat. From that point on, Nibbles will remain a permanent resident in the apartment.
