Cats, particularly kittens. I do a whole lot of fostering, particularly with very young and/or sick kittens. At this very moment, I have 16 fosters from 4 different litters.
It sounds to me that Bubi's previous experiences with travel/moving and other cats happened before she lost an eye? How long ago was that? That has the potential to make all these upcoming changes even more stressful for her than they were when she was younger (more adaptable) and had both eyes.
I understand the temptation to add a new cat when the territory is new for both, but I think it would be much kinder to Bubi to try and minimize the number of new things she has to adjust to at once. You could designate a room in the new place that Bubi won't have access to as the room where a new cat would eventually start out. That would allow Bubi to acclimate to her new home, and then when she's ready, you still have a space for the new cat to start out in that isn't actually taking any territory away from Bubi.
If you want to adopt a kitten, I strongly recommend adopting 2 kittens. Kittens have waaaay more energy than most 4 year old cats, so a single kitten is likely to annoy Bubi. With 2 (or more!) kittens, they'll have an appropriate playmate around with a similar energy level, and Bubi will be free to engage only as much as she wishes to. If you're set on only one more cat, an older kitten (6+ months) or adult cat might be a better choice. You could also look into fostering as a way to test the waters without a full lifetime commitment.
Also, I highly recommend Jackson Galaxy's guide to cat introductions. There's 5 parts:
I mostly hung out with some of the "weird" kids. I think it was 5th or 6th grade when I decided that I wanted to hang out with the popular kids, and I guess I managed to succeed, because a year or two later, one of my classmates told me how popular I had been. I never felt popular though, and the time I spent trying to be popular was just constant stress because almost everyone else in that group is also worried about being accepted.
Nope. I haven't bought anything other than a Pixel since they were known as Nexus. Originally because they were cheap, but decent, then because they were easy to tinker with, and now because it's the only phone that runs Graphene OS. If I need to buy a new phone, I just look for whichever Pixel is cheapest, and that's my new phone.
Looks like a Maine Coon, so probably came from a breeder, and while it's not an area I've really dug into, it looks like there are some Maine Coon breeders producing cats with blue eyes. Could naturally be blue, but the brightness definitely seems artificial.
Yeah, as far as I'm aware (and I spend way too much time reading about cat coat genetics), that combination of colors could only happen in a cat with 2 unique sets of DNA. I would still call that a tortie, though.
That blue eye though, I don't know enough about eye color genetics to confidently say, but the other features of the cat look like a Maine Coon, so it is possible that this cat came from a breder and there was intentional selection for eye color.
Cats. I probably argue too much with people about the "correct" descriptions of coat colors/patterns, as I really like learning about the genetics behind them. Lots of other cat related stuff too, such as diet & training/behavior.
What are you feeding them? A friend of mine was complaining about extra stinky poops a while back, and some dietary changes made a huge difference in the smell. Doesn't explain why this box is smellier, but could be an alternative solution to your problem.
I also used to let my cat hide in the back seat until someone reminded me that if the vehicle has to stop suddenly or is involved in a collision, the cat could go flying. It's much safer for them and for you for them to be in a carrier, and the carrier buckled in, or at least wedged in somewhere.
As the other person noted, pill pockets or pill wraps help a lot. My more difficult cat initially kept spitting them out even with the wrap, but he eventually learned that I'm going to try again and again, and he doesn't get the treats until he swallows, so now he's pretty good at swallowing on the first try AND I can get away with the occasional unwrapped pill.
The other trick I used was using my younger cat to help train the older one. I started off using a syringe of water, followed by treats to get them used to the general process and the understanding that they get treats after. My younger cat would line up for another syringe of water knowing he would get treats, so we'd do a few rounds of syringe water every evening, and I just kept doing that until the older cat got curious enough to voluntarily participate. Once they were both voluntarily participating in the syringed water, they would at least come to me for pills, so the only fighting was to get them to swallow.
Some tricks to encourage swallowing include holding their mouth shut and stroking the underside of their neck, and/or following that pill immediately with a syringe of water.
My oldest loves to explore the kitchen counters at 3a. Last week, I found the huge glass jar that I store his kibble in knocked on its side, but thankfully not broken.
