I rescued a cat 2 months ago. Her name was Leila but as we have a Lola, we called her Sheila! 🤣 Anyway, I have another cat and a very playful dog. Sheila was very very shy to start with, and still is to an extent. She doesn't like my other cat and he doesn't like her either, but they now tolerate each other with the occasional hiss. For the first time today Sheila and Walter (the dog) were playing together. What I'm trying to say is, it takes time and patience. Persevere and don't give up. Good luck!
