Hi,
Do the research needed. Look at what papar work is needed. Breeding equipment needed ie heat pads, foster bottles etc. You must consider that if you work, you need to be with your queen when she gives birth. Also if some kittens need bottle feeding throughout the day and night. Then to consider vets fees. ( Like if your queen gives birth at midnight, which they do. If vets treatment is needed it could cost over £100. ) Breeding any animal should be done with great care and attention, also with lots of love.
