Era stopped notifying me about this thread (happens a lot in OT threads for me) and I was in an indie game convention showing off my game anyway, so I'm going to focus on answering people asking questions, but thanks a ton to everyone for their kitty pics!
The first cat we did did that when we left her alone; she stopped doing it once we got more cats. It's typically boredom or stress; being alone is really hard on cats, especially of intelligent / social breeds like siamese and abyssinian. If there's not at least one person in the house with him, I would dearly, dearly recommend you get at least a second cat. Cats are really good at hiding their pain and discomfort, of any kind (which is a problem when it's a life-threatening issue), so you have to be attentive to secondary signs like these. Think of it as smoking or chewing one's nails.
If getting another cat is absolutely and positively out of the question, you can try to protect your cables by sticking sellotape to them (sticky side out), or spraying them with lemon juice. It's kind of a chore and not foolproof but it may be better than nothing.
Exactly this.
The latter is a very strong sign that the problem with your cat is a deficit of social interaction and boredom.
Don't ever bathe indoor cats unless absolutely necessary (e.g. something nasty poured on them). Cats are exceedingly good at self-cleaning and bathing them not only stressed them but also removes natural oils from their fur.
This can actually be a chicked / egg scenario: not sleeping with you means he's alone for longer, which exacerbates the issue as mentioned above.
Try to have lots of water bowls, and make sure they're separate from both food and litter (see the OP). A cat fountain can also help with that. A diet of exclusively (canned) wet food can lead to obesity, especially after spaying, which obviously has its own issues and complications, so it's optimal to make sure he does drink.
Hahah, never worry about posting too many cat pics in this thread.
He's utterly wrong; I would advice to change vets if you can. I'm not even kidding, a vet that tells you a cat bell "barely matters" doesn't know what the fuck he's doing.
Outside of that, of course, it's a decision you have to make for yourself, but personally I strongly recommend against it, especially on a cat that you already know has signs of stress problems like cable chewing.
Could you define in more detail "goes absolutely insane"? A lot of cats have a tendency to run like crazy after pooping because it's when they're most vulnerable and the smell can attract predators. Is it something like that?
Haha by absolute insane i meant compared to his normal behaviour. He just runs like he has a lot of energy back and forth, his eyes get massive and he likes jumping around playing with his toys or with us. He also loves playing chase with us during that period.
The Vet said it was euphoria and that it's common. Nothing crazy, it's just Socks being.. Socks
