I mean, to non-horse-cat-dog people, all three can be quite gross. Dogs smell unless consistently bathed (I have a dog that rolls in horse shite almost daily - found that out after he was allowed in the bed.
) They generally shed and track in mud and dirt. Cats generally do not smell but shed and vomit hairballs. My latest cat whom I recently euthanized due to cancer was vomiting and not using the litterbox in her last days. I am constantly cleaning mud and dirt that is tracked in from working outside with horses. Let alone how filthy and smelly I get, along with my clothes. I don’t think it’s necessary fair to write off your husband’s feelings about this because there may be legitimacy to his feelings. There may also be other things going on. Regardless, you must live with him. I would ask specifically what’s bothering him because it could be something you wouldn’t automatically assume.
Some things I do to manage it all -
I bought a robot vacuum and run in frequently. I love the little thing. I also have a very convenient stick vac that I use.
I’ve rerouted traffic to a specific area to contain the dirt. I established a sacrifice area for all of the muddy items or outdoor clothes, shoes, etc. I also established specific spaces for tack that flows into the house and keep it organized.
I don’t allow said poop covered dog in my bed or on furniture anymore and if the dog is inside, he is bathed regularly and brushed. Dogs smell and we get used to the smell. Ask you SO if part of the issue is where the animals sleep.
I bought a robot litterbox that flushes the litter. More sanitary, less smell. I also brushed the cat more.
We got rid of all the carpet. Hardwood has been much easier with animals. Any animal bedding is constantly cleaned.
You get the idea. Also, I use to have difficulty buying new things as well for a plethora of issues. Sometimes still do. What makes it easier for me is waiting until I find something I absolutely love. If I feel strongly about it, I buy it because I know I will cherish it. I also think decorating your house can go a long way. We had our house minimally decorated while renovating and adding the cozy touches really does make a difference in my quality of life. Find things you find meaningful and don’t overwhelm or rush yourself in the process.
