Just wanted to wish Cujo well for his surgery, and for a quick recovery.
I am sure that he will do great.
I brought Maddie home, same day for her spay, and she was very groggy, I just made sure that she ate a good meal and let her get lots of sleep. I used the onsie the first 3 days, it helped keep her out of the stitches. but some don't bother the stitches.
