My cat Cleo for the past 2 days, hasn't all been herself. Yesterday she stayed in her kitty condo, only coming out to use the bathroom, eat, and drink and then to return back to where she was. When she walks she is scrunched up in the back, and she growls when I touch her stomach. Her stomach does look a little swolen like she bloat. Can anyone tell me what is wrong with her and what I can do to make her feel better?
