Thank you so much!!
What size do you recommend for my SNickers? He is 4lbs (on a good day, usually 3.5lbs) and about 14 inches long from nose to tail. I think the large might be right since the small is 15 inches long (might be a tight fit.) Snick is tiny but I think the large might be roomy so maybe I can put a light blanket in it on colder days or if he is wearing clothing.
Let me know your opinion.
Thanks
