She is 4 months and one week and I'm worried she is overweight. She has two meals a day and treats. She has 1 pouch of felix a day mixed with Purina Pro plan. Treats wise she has a few dreamies at bed time She is very active. But she is growing fast. She has loose skin on her belly. I've never had a cat and sure if she is normal. I don't want her to be unhealthy.
