Over the last 15 years of our animal ownership we had: 6 horses - sold 4 dogs 3 english setters and 1 beagle - all passed away countless barn cats - still there 4 geese - still there 3 ducks - still there numerous chickens - still there hamsters- not sure what happened to them - cats probably!
DO NOT get horses. We did that whole thing with making hay too. Besides food costs you will have constant vet bills (and they charge you drive time), ferrier bills every 6 weeks, tack costs, training costs. Then "we" decided to show the horses. Trailer costs, show clothes, fuel to get to the shows, hotel costs. If you decide to leave for a vacation you have to pay someone to come over and feed/water them. And we had property to raise hay, all the equipment and our own barn. All of the rest of our hobbies, classic cars, hunting and fishing do not even come close to the cost of horses. We called them hay burners towards the end. The critters we have now can be left alone for up to a week with no issues.
