|| Penny and Mr. V!

Miss B is a Siamese cat, a scientist and the "boss" of Groshi and Mister V, who wears glasses.
She has a well-groomed coat and a “business-like” appearance.
Serious and a little rude, but still ready to help and very kind inside.

Grosha is a street cat who knows the city and its inhabitants well. He also works for the Special Investigation Bureau and sincerely considers himself the chief detective. For him, investigation is an adventure, not a dry, fact-finding exercise.
Groshi has a more casual, unpretentious appearance than the elegant Mr. V: his brown fur is slightly tousled, as if he's just run halfway across town, and his appearance is energetic and slightly mischievous. He immediately exudes that street-wise spirit: lively, agile, and always ready to take off.
Impulsive and energetic, Grosha acts quickly: if he finds a clue, he immediately follows it without wasting time on deliberation.
He trusts his instincts and sense of smell. His main tools in investigations are smell and intuition. He can tell where someone has been by scent and instantly read the mood of his interlocutors.
Straightforward and emotional, Grosha doesn't hide his feelings: if he's upset about something, he says so right away; if he's happy, he doesn't hide his delight. Because of this, he often argues with the unflappable Mr. V.
Inquisitive and bold. Curiosity is in his blood: he goes to the most unexpected places to find clues, and he's not afraid to get into the thick of things.

Mr. V is an elegant Persian cat, a true gentleman and thoughtful detective. He works in the Special Investigation Bureau alongside his partner, Grosha, and proudly bears the title of "Very Important Detective." He has a lush gray-blue coat and always appears well-groomed and understatedly stylish. A constant detail of his appearance is his bowler hat, which emphasizes his seriousness and his affiliation with the "old school" of detective work.
Reasonable and calm, Mr. V almost never loses his composure—even in the most confusing and absurd situations, he remains unperturbed.
Relies on logic. Unlike the impulsive Groshi, who trusts his instincts and intuition, Mr. V analyzes everything carefully, builds chains of reasoning, and calculates options several steps ahead.
Polite and well-mannered, he speaks with restraint, treats others with respect, and even tries to be patient with his hot-tempered partner.
