We are looking for a house sitter (I'd say "apartment sitter") for our cat. He's already one, almost two years old, but we just adopted him about a month ago and would feel so bad for him if he were alone all day. I feel like he's a typical male teenage cat: He wants to be around people, wants to play, but doesn't want to be touched. haha He loves coming up to you and cuddling, but on his terms. Work involved would be scooping out clumps of a litty litter once a day (we'd leave it full and ready for you, so you wouldn't have to change it), feeding him once or twice a day (depends on how quickly he eats that day), refilling his water every once in a while, and maybe play with him once or twice a day. He's an amazing jumper. Try throwing things in the air.
The apartment is in the city of Las Palmas, not on the beach, but there are two buses that stop right in front of our building that go either to the beach (Puerto) or the old town (Las Palmas). If you have a car, you can be at the beach in 10 minutes, and there's a great parking place for € hours right next to Las Canteras.
