11. "Rescued my boy Jasper in 2019. My grandfather found him along with 2 other kittens in an abandoned house. When I first rescued him he was dirty, skinny and very scared. He was the shyest one of the litter. My family told me not to keep him because he was 'mean'... He would hiss, growl and swat. I knew he was just scared and needed time to get used to a new environment and humans. With time he became more and more confident. Now a year later, he is the most loving, goofiest, dog-like cat I could of ever asked for. He is always by my side and constantly begs for attention. I couldn’t imagine life without him.... #thenandnowchallenge"

12. "Bane started off afraid of the ocean, hiding by the rocks. Now he jumps in the waves and it’s his favorite place 🥰 #thenandnowchallenge"
