Our cat Pickachu has settled back in to our home as the one and only cat . I cant say he seems disappointed . We have decided that we are not going to try for another cat again. As much as we would love to help and adopt more my husband is scared that the allergies may return. Since things have calmed back down I have noticed that our cat is being very mischievous, more than usual. I just wondered if that was normal. He has started knocking his water in the floor... several times a day .. and every time I put water back in his bowl he knocks it out.... Also we have a balcony and he has been teasing an injury i feel like by running across it .. I can tell that he is enjoying having the house to himself. Does anyone have any suggestions on how to stop him from knocking the water over?
