i have three plus and it is not bad (really!) ... as far as the vet appts go, they are all different ages so the vet appt are all spread out throughout the year
yes it is more work to feed them (since they cannot be free fed because bentley is a huge piggy

) and it takes about 30 minutes for meals...we split up bath days and do baths over two days...we brush teeth every other night and use petzlife in between brushings...it takes a while to get us all ready for bed lol
it is not really that bad but (1) i have help and (2) i do not have 2 legged kids (and never will) ... i am sure if either of those things were not the case, it would be too much work
