I suggest locking your cat up when birds are there, (NOT CRUELY!!!) or put something the cat hates by the doorstep. Or maybe just distract the cat, which doesnt really work by the way, or put the birds area higher in a tree.
Yes. more so a caged bird as it cannot get away from the cat
Communities do not generally have laws prohibiting cats from running free, but there are ways to keep them away from your bird feeder. The most obvious is to position the feeder high enough off the ground and far enough from trees and branches so the cat can't get at it. If this doesn't help, there are sprays and electronic deterrents such as CatStop (which should cost less than $50). Also, you say you have a dog. If your yard is fenced, you might try keeping him in the area near the bird feeders. Cats generally don't hang around dogs.
probably their owners have moved from the area and taken them with them
No, bird fleas cannot get into cats. There are different kinds of fleas.

Obivious cats are you stupid?

Currently you can tame wolves into dogs by feeding them bones and you can tame cats by feeding them fish.
Feeding balls provide mental stimulation and slow down eating, promoting healthier digestion and reducing the risk of obesity in cats.
Using a multi-cat food bowl for feeding multiple cats can help reduce mealtime stress and competition among cats. It can also promote healthier eating habits and prevent food aggression. Additionally, it can make feeding multiple cats more convenient and organized.
Feeding chives to cats can be harmful because they contain compounds that can cause digestive issues, anemia, and damage to red blood cells in cats. It is best to avoid giving chives to cats to prevent any potential health risks.
It is almost impossible to just keep them away from nests, unless you have full attention on them when they go outside, or keep the cat inside at all times. There are "cat deterrents" that can help discourage cats from entering a certain area, but most are not 100% cat proof. These deterrents include using predator urine (be careful not to use urine from a predator known to frequent your area as it might be an attractant to that predator), mulch with strong odors that can't don't like (like citrus, cocoa), or ultrasonic devices. Best choice is to keep the cat confined to a yard or area with cat-proof fencing.
