The sort of thing I worry about is like, well yesterday my brother's girlfriend Heather came over. She comes over a lot, like four times a week, so she doesn't exactly follow normal guest etiquette and we don't treat her like a normal guest. We had some chips and dip in the living room and Tucker jumped onto the couch next to her and she immediately shoved him off because she was eating. Now, he didn't do anything when she did this, but he could have. It's something like that I want him to be able to deal with without getting growly or snapping (and I feel like if dad did the same thing he would have growled at him). Because things like that are going to happen sometimes when it doesn't cross someones mind that he might become aggressive. Maybe just by drastically cutting down the number of times we move him he'll be less annoyed by it the few times we do. After she shoved him off I started petting him for not trying to eat her and she rolled her eyes and said "C'mon Erin, he can be on the floor for 5 minutes, he'll live" and I sort of wanted to punch her in the face. She doesn't know he's been growling, I don't really want to hear her opinions on the matter. She always has opinions and their rarely educated ones.
I bought a container for treats in the living room and put the zukes in it. The cats knocked it down last night, somehow unscrewed the top, and ate most of them. I had a brick in front of it so I thought they couldn't get it off. Very stupid assumption. Hopefully today or tomorrow someone will take me to the pet store to buy some of the Stella and Chewy's if they have it.
I appreciate everyone's advice, Hopefully I can get everyone to start using their words instead of their hands and to think before they act (this is always mom's defense, she/they didn't have time to think about it, she/they just reacted).
