Male 2 year old cat and 12 week old kitten (Silver Spring)

Male is 2 years of age and his daughter is 12 weeks as of today. Both are litter trained and very laid back. Both get along with all animals. Currently living with a Yorkie and they sometimes sleep together in the dog bed. Rehoming fee of $250 is being asked. The do not have to go together but I would love for them to stay together.
