Okay here is just my opinion....I dont understand why vets keep babies overnight after spay/extraction. It is much less stressful on your baby to be home with you and comfy in her own bed. I am sure some love the fact keeps them and moniters tham but Does your vet stay there all night with her? Either way he is probably going to be a phone call away. Im just a fan of bringing them home. My vet did Bellas Surgery at 8 am I was able to pick her up at 6 pm. SHe also was 2 pounds or so and 6 months. She has 9-12 teeth pulled (cannot remember exactly) Again just my opinion and preference. I wish your baby luck>
