Are Javanese cats good pets?

Yes, Javanese cats are good pets. They have an affectionate and playful nature, often enjoying interactive play and being involved in family activities. They’re also quite intelligent and social, thriving in environments where they get plenty of attention and mental stimulation. If you’re looking for a lively and loving companion, a Javanese could be a great fit. 

Just keep in mind they do enjoy having company, so they might not do as well if left alone for long periods.
