2 cute sibling kittens 4 months old (Alvin)

They are both black and white have been weaned. I think they might be girls not 100% sure yet. I am getting them fixed in 3 weeks. They are litter trained and sleep solid at night. I will take a re homing fee if you get them after I fix them if before, then free. I have the the appointment to fix them at snip in League city Oct 24th. The momma kitty is still on a 2nd litter currently, so I need to get these homed ASAP.
