Our new kitties are coming home tomorrow! They were abandoned starved in a box and covered in spray paint 
. They have been in foster until now. I'm stressing about doing everything right, for the new babies but also for our 15 year old cat. I have been reading up on here and have my feliway plugged in, the spare room set up for the new arrivals, cloths for scent swapping. Beds, toys, litter tray, same food they have been on until now. They are fully vaccinated but not yet spayed. How soon should I get that done? They won't be going out before that obviously, but I don't want to stress them too soon with an op? They are around 17 weeks, not sure if siblings but close in age and very bonded. Please pass on any words of wisdom and advice!!!
