You'll have to forgive the poor quality. The new iPhone doesn't come out until next month.
It's been 16 days since I brought the kittens home. Not bad right? Chloe (the bigger cat on the left) used to hiss and growl all the time. Now she will tolerate cuddling from them and even cries at the door to be let in. All of them are using the upstairs litter box fine and have no problems eating next to each other.
For my first ever attempt in introducing new kittens to older cats, I think it went well and I am rather pleased with myself. Hahah, yes I'm going to gloat a little and give myself a good pat on the back!
