I'm fairly certain my cat has separation anxiety
Long story short, when I lived with my friend he was home all day everyday with the cat, I had to move and I took my cat with me as he is quite attached to me as well. He is fine when I go to work albeit a bit of loud crying at the door for a minute or so...However, once a month I go out of town 2 hours away to see this friend that the cat and I used to live with. I'll stay for 3 nights at a time.
While I'm gone however my family tells me he acts out terribly. Pees on things (not just my things), picks fights with the other cats, he rips up toilet paper rolls, all the bad things...he is already being territorial here and pees occasionally, but he is worse the weekends i'm away. He really does throw temper tantrums. You scold him and he'll "cry".
My question is should I just take him with me or would it just be too stressful? Would it hurt him too much to see my friend again and then not see him (he hasn't seen my friend in about 4 months, and not for 2 months before that) It would be a Fri, Sat and Sun night, being back home Monday morning/afternoon. And me and my friend would not be out for more than a few hours at a time. He does pretty okay in a car, he has a huge amount of trust in both me and my friend so as long as we are the ones to do something, he trusts us (isn't scared of the vacuum, car ride, going outside, etc as long as its with us). However, he would be confined to one room possibly and it would not be the apartment we both lived in before. There is one 2-3month old miniature schnauzer, but it stays in a kennel (too much time in it in my opinion, but it's not my dog...)
Really want to know what to do...tired of my family making him out as just a bad cat when its not him, it's me? And also hate coming back and picking up after him. But also afraid I'll do more harm than good, by "giving in" or letting hi see my friend again...
Cat background:
He is a Korat and is about 3-4 years old. Neutered. He has a younger girl cat he has as a "rough housing" playmate. Sometimes a little too rough because she is really small, but she doesn't back off either. He also has an older half sister (about 7 years old) that he used to bully all the time when she also lived with me and my friend. He doesn't bully her anymore since he got his playmate. His half sister sleeps and keeps to herself. He is getting along with another older female now younger than 7 years (they sleep together occasionally, but sometimes he really bullies her meanly too, but not often because she's bigger than him) *the above paragraph is all while I'm here*They are all Korats*No other males in house*
