Tilly is a sweet cat overall, who only suffers from a bit too much enthusiasm at times. Most time, she is sweet as pie and will not bother you. But if you play with her, and get her too riled up, she can play quite aggressively, using her claws and biting. She doesn't pull her punches. So she needs to be an only cat in the house (Tilly also doesn't like other cats) and she needs to have an experienced cat owner, who is not surprised when cat play gets rough. She is affectionate and sweet at all other times.
